Chapter 2: What are the BVR Cables?
BVR cable is a sort of soft wire for division cabinets. BVR cables are also known as Secondary wire. BVR cable is a soft wire which is insulated by using copper-core polyvinyl chloride.
It is also known as the BVR line.
This kind of wires is used in those areas or those applications where we need flexible wiring. BVR cables are admired by mostly electricians and other building decorating persons.
BVR cables are insulated and sheathed with PVC. These wires are used in various applications like fixed wiring to flexible installation of wires. These cables are available in different sizes and various colors.
These cables are suitable in areas where you need protection from UV rays to prevent cables from decay. BVR cables are highly suitable for low and medium voltage cables.
These cables can also be used where low-frequency installation is required.
B series products are basically composed of cloth wire, thus it begins with letter B. Voltage of these cables is 300/500 V.
Here, V represents PVC, which is basically plastic. The meaning of R is soft, soft means to increase the number of conductors, for example; BVR copper core PVC insulated soft cables.
BVR wires are specially developed for various power devices. These cables are used for fixed wirings and for flexible appliances for AC rated voltage up to 450/500.
Chapter 3: How BVR cables are constructed?
What is the structure of BVR Cables?
BVR cables are fabricated with insulated PVC. They are made up of copper. They are manufactured with conductor plus insulation.
The sheath material used in the construction of BVR cables is polyvinyl chloride.
Copper, aluminum or solid strand is used as the conductor in BVR cables. It can be a single-core or multicore.
Both the insulation and BVR’s sheath materials contain PVC.
The major component is a conductor and it contains oxygen-free copper. The conductor is formed with multiple copper wires.
Their sheath color can also be customized according to the requirements of the customers. They are manufactured in compliance with the desires of the clients.
They are packed in a plastic reel or paper reel. They can also be packed in wooden drums.
They are manufactured on different occasions. So, different material is used accordingly.
For instance, BVR cables used in electrical instruments consist of copper core PVC soft wire. Similarly, ZR-BVR cables are made up of copper core PVC. To work on fire-resistant occasions, the flame retardant soft wire is also used.
As BVR are cables are armored with PVC so, we can say that PVC cannot conduct electricity. BVR cables are best to use for wiring of your houses or buildings as they are PVC coated. Thus, there are fewer chances of electric shocks for them.
PVC which is used in BVR cables stands for Polyvinyl chloride. Polyvinyl chloride is basically a sort of thermoplastic material. Polyvinyl is very flexible and handy.
It was since the 1950s when rubber sheathed cables were replaced with PVC. They were replaced because of ease of processing in household wirings. PVC is used in BVR cables as it is cost-effective and has long-lasting features. It usually exceeds thirty years’ service life.
PVC is a very well-known compound that is used on a large scale. Polyvinyl chloride has a lot of characteristics that explain why it is used for wire insulation.
Polyvinyl is also used for cable jacking. Polyvinyl chloride has a lot of properties like it is durable and UV resistant. They also resist chemicals and water.
That’s the reason why they are being used in the preparation of BVR cables. Due to PVC, BVR cables work as a versatile product as its properties can be simply altered.
It is easily altered with lubricants, stabilizers as well as plasticizers. It is also simple to recycle when it is utilized as a thermoplastic type.
PVC is used widely for the construction of electrical cables for insulating purposes. PVC is also used for bedding and sheathing of electrical wires.
PVC is beneficial as cable insulation because of its chemical solidity, its strength, and its durability. Polyvinyl is much more easy to handle and easy to strip.
In this modern age, Polyvinylchloride produced is resistant to fire as well as water.
If polyvinyl chloride is used in high-risk zones it is still good to require a low smoke and low halogen grade. The normal PVC wires are mainly used in electrical wirings of houses and buildings.
Chapter 4: What are the different models available of BVR Cables?
BVR Model
BVR is a copper core PVC wire. It is produced with PVC soft wire. It is used in power instruments.

It is also used in telecommunications equipment in fire-retardant occasions.
NH-BVR Model
This model of BVR cable is also consist of copper core PVC and flame-resistant soft wire. It is used in control circuits and monitoring circuits.
It can also be utilized in line protection and large scale constructions. Petroleum, cable ship, and chemical industry also take benefits from NH-BVR cables.
Personnel-intensive and metallurgy industries usually have greater fire-retardant requirements. So, they also have an NH-BVR model of wires in their use.
Chapter 5: What are the features of BVR Cables?
BVR wires have a variety of features.
- Their enduring and durable permissible working temperature does not go beyond 70 ℃.
- Their laying temperature does not be less than 0 ℃.
- The outer diameter of the BVR cable is less than 25 millimeters. The bending radius of the cable is not less than 4D.
- The outer diameter of the BVR cable is less than 25 millimeters. The bending radius of the cable is not less than 4D.
- The outer diameter of the BVR cable is 25 millimeters or above. The bending radius of the cable is not less than 4D.
BVR cables are a type of PVC, so we can say that Vinyl can be used for multiple purposes. These wires can be flexible.
They can be like a plastic covering. BVR cables can be like a wallcovering. It means they can be thin and flexible. They can be available in any matched color.
Most of the BVR cables produced are used in construction and building applications. These cables are very efficient in protecting the environment for better transmission. It means, there are chances of low greenhouse gas releases and energy.
BVR cables are strong, stiff and can resist moisture. These wires are secure for the transmission of electricity as no other signals can intercept that transmission.
BVR cables provides resistance against chemical and electrical erosion.
As these wires have a resilient sheath.
They can’t get affected by vibrations.
BVR cables are also able to decrease the dielectric losses in many electrical applications.
In this age, everyone is demanding for electrical cables. Because there are much more ongoing constructions and electrification.
With the passage of time, old wirings have to be exchanged by the latest wirings. So that electrical applications can work properly and efficiently.
Seeing the desires of the marketplace, BVR cables are a very efficient and ideal solution. Because these cables are cost-effective, and have higher conductivity.
BVR cables also offer insulation contrary to any electrical faults.
It is similar to home lighting. It can also be utilized inside the buildings and indoor constructions. It can also be used for tube piercing.
It can be classified into different colors such as red, blue, green, yellow, black and white. It is classified to clear the difference during the installation process.
Among BVR cables, low smoke halogen cables release a handful of smoke under the situation of flame ignition.
The gases produced by low smoke halogen cables do not include halogen elements. Also, they are non-toxic.
Because of their characteristics, they can reduce the danger of equipment during fire. Furthermore, they work as a safeguard for the instruments, high buildings, hospitals, and stations.
They are very useful in gymnasiums, dispatching building, underground stores in alarming situations.
In the case of electrical wirings, durability is one of the most important factors. BVR cables are too much durable. It means you don’t have to worry about changing your wirings anytime soon.
SSG is providing you durable, compatible and much efficient BVR cables.
