A mining cable is a special type of a retardant cable that is manufactured to be used to tough or unfriendly conditions. One of such places is in the mining setup where the conditions seem to be quite unfriendly.
A typical mining cable can easily withstand torsional and tensile stress without having any physical or structural defect. It can also be subjected to the never-ending winding over a long distance. In short, mining cables are designed to operate in the harshest environments in the earth and even beyond the universe.
The quality of the mining cables helps to minimize the risk of equipment failure or operational downtime during the mining process. The cables also pacify the safety aspect of the working environment.
Apart from the mechanical forces, mining cables are designed to resist various physical elements. They include water, grease, oil, smoke and even heat. This explains why mining cables can be used anywhere without any problem. The cables can be used in both open and closed spaces.
Chapter 2: Characteristics of a Mining Cable
Mining cables are indeed unique. So, what is the unique thing about them? The features and characteristics of these cables are the main things that make these cables unique.
Here are some of the unique characteristics of mining cables:
-Resistant to temperatures
It is quite obvious that a mining environment is characterized by an extreme temperature range.
The place can be extremely hot or too cold. Such temperature can easily affect the effectiveness of the tools around, including the cables.
The good news is mining cables are designed to withstand such unfriendly temperature conditions.
Even when it gets too cold or too hot, the quality and reliability of a mining cable won’t fade. It will still be able to perform to the optimum levels.
-Not affected by the climatic conditions
Mining cables are bullet-proof when it comes to the weather and climatic conditions. They are not affected by such factors.
This is to stay that you can install these cables anywhere you want without worrying about weather conditions such as rainfall, storm draught, humidity among others.
-Resistant to the ultraviolet radiation
Ultraviolet radiation (UV) rays are among the most destructive radiation that tends to affect the quality of most cables.
The good news is mining cables are fully protected from the UV rays. They cannot penetrate through these cables to cause any form of damage.
-Maximum electrical isolation
Electrical isolation implies the ability of the cable to prevent loss of current that is flowing through it.
The conductor in the mining cable is properly enclosed to protect it from all forms of interference.
With complete electrical isolation, we can boldly say that these cables are reliable.
-High carrying capacity
The carrying capacity of a cable is the amount of current and subsequent voltage that can be carried by the cable. The capacity can be high or low.
Mining cable has a high carrying capacity. They can be used for both low and high voltage applications.
When it comes to drawing a comparison, the carrying capacity of mining cable is assumed to be 50% more than that of PVC and rubber cables.
-Resistant to chemicals and solvents
During mining activities, there are chemicals and other solvents that are used. Chances are such chemicals and solvents can get into direct contact with the cables. If you are using ordinary cheap cables, they can get corroded and even damaged.
Apart from chemicals, mining cable is biologically inert. This means that it does not react with biological elements which can have a negative impact.
The cable does not react and sticks with other materials that are used in the mining activities.
From these characteristics, some of the things that stand out are the strength and durability of the mining cable.
They are cables that can perform to their maximum potential and serve you excellently without failing.
Chapter 3: Types of Mining Cable
Cables that are used in mines are divided into two main categories. These are trailing cables and the pliable armor cables. Let’s look at what each of these two cables has and which one you should buy.
1. Trail mining cables
Most modern mining cables tend to fall under this category.
A trailing cable has five cores. Three of them are power cores which are used for the phase A.C supply. The fourth core acts as the pilot while the fifth one is for the earth.
The trailing cables are insulated with synthetic insulating materials such as Ethylene Propylene Rubber (E.P.R) and Chloro Sulphonated Polyethylene (C.S.P).
The two insulating materials are quite strong and tend to give the mining cables their character.
The cores in the trailing mining cables are arranged in different patterns to avoid exerting stress or pressure on each other.
These cables are screened separately or individually. The purpose of the screening is to provide maximum electrical protection for the conductors in case they are damaged or something manages to penetrate them.
The screening can be done using copper or a conductive rubber screen.
2. Pliable Wire Armoured Mining cables
These mining cables are characterized by four cores and synthetic insulation on each core.
The main types of insulation that are used on these cores are the C.S.P and the E.P.R.
When it comes to the carrying capacity, the cables can be used for both low and high voltage needs.
The cores of these cables are laid up around a center then enclosed in a sheath. Copper and nylon braids are used for screening these cables.
Chapter 4: Methods of Installing a Mining Cable
After buying the mining cable in China, the next step is to install them.
Not all the sites where you would like to install these cables are the same. This means that there are different ways of installing mining cables.
We are going to discuss some of the safest and effective ways of installing mining cables.
- Suspension: This mode of installation involves suspending the cable with the help of wires, hooks, and walls. Sometimes braided suspenders are used for suspending the cables freely.
- Using cleats: Cleats are usually used where the mining cable is supposed to run along with a building or any other massive structure.
- Duct: In this method of installation, trenches are dug then lined up with bricks and concrete for extra strength. A mining cable is then fastened to the wall of the duct using brackets or even cleats.
- Wall and Brackets: here a mining cable is directly rested to the brackets which are then bolted to a wall. This method is ideal when you want to install the cable in a closed space.
- Trench: When you want to install a mining cable in an open site, you should consider using this method of cable installation.
It simply entails laying a cable in a trench or a bed of sand then covering it.
The trench can be pacified tiles for strength.
6: Shaft method of cable installation: Here you can install a mining cable by putting it in the shaft then clamping it using the wooden cleats. You can use cleats of different sizes to clamp the cable.
For safety purposes, it is advisable to mark the trenches with posts to prevent any undesignated human activity around the area.
Chapter 5: Applications of Mining Cables

Just because they are known mining cables does not mean that they are used in places where minerals are mined.
This name is only used to imply that the cables can perfectly survive in a harsh environment such as mining sites.
Otherwise, mining cables have a wide range of applications, including in places where there are zero mining activities.
Given their characteristics, mining cables are used in applications where the cables are likely to be subjected to high mechanical stress, torsional stress, and tensile stress.
The cables are also the best option where there is a need for frequent winding of the cables.
Are you experiencing unfriendly weather patterns in your area? Mining cable may be the perfect option. They are rarely affected by harsh weather conditions.
They are also the ideal choice of cables for dry and wet places.
A mining cable is also a perfect choice for handling equipment in motion. This is because the cables can be subjected to cycles of winding and unwinding without experiencing any physical damage.
Some of the most common applications of a mining cable include:
-In mining sites
-In steel and metal mills
-In airport lighting systems
-In ships and other water vehicles
-EOT (electric overhead traveling) cranes
-In construction sites
-On textile machines
-Windmills and water power turbines and nuclear power generators
A mining cable is an ideal choice in any other application where you are doubting about the capability of ordinary cables.
Chapter 6: Factors to Consider when Buying Mining Cable
Mining cable specifications are different. They vary from one cable to another.
This means that when buying a mining cable in China, you need to be extra careful to avoid getting a wrong cable.
Here are some key factors that you should consider when choosing a mining cable in China:
1. Maximum continuous current rating of the mining cable
Like any other electrical cable, a mining cable must have the maximum amount of current that it can transport under different conditions.
The maximum continuous current rating of the cable takes care of key factors such as the temperature rise that the cable can withstand.
The temperature can be from the heat generated by the cable or even temperature of the surrounding environment such as soil.
From the continuous current rating, you will be able to tell whether the cable is suitable for your application.
2. The voltage drop:
The voltage drop of the mining cable should be within the required limits. Of course, your area of application will determine the acceptable limit for the voltage drop.
3. Physical condition for the installation
Where you are planning to install a mining cable matters. Whether you are planning to suspend the cable or install it underground, you should choose a cable that will match with the condition of the installation.
The condition should cause serious damage to the cable through corrosion, abrasions or even stress.
4. Expected temperature rise
In the case of a short circuit in the cable, there will be an unprecedented rise in temperature. Check if the cable can withstand extreme temperature without getting damaged.
Apart from the short circuit temperature, the cable should also be able to withstand the temperature that is caused by external factors.
5. Earthing of the cable
Check the cable to see whether it is earthed or unearthed. You will save some good money just by looking at this factor.
If the cable is earthed, you will not have to install an earthing cable during the installation. On the other hand, unearthed mining cables will require some modification which can be quite an expensive affair.
You will have to buy a separate earthing cable.
6. The cost of mining cable
You should remember to do an economic evaluation of the mining cable. This is to find out the price of the mining cable for sale.
From the cost, you will be in a position to budget properly for the cables.
