BVR cable is a copper core PVC insulated flexible wire, which is used in places where flexible wiring is required for fixed wiring.
Commodity structure: conductor + insulation. The main material of the conductor is mostly oxygen-free copper, consisting of multiple strands of copper wire, and the insulation is PVC;
Implementation specifications: JB8734-98 / GB5023-2008;
Quality specification: 3C certification;
Extra voltage of overhead line : The wire is immersed in water for 1 hour, and it is forbidden to be subjected to AC 50Hz 250V (450 / 750V) and 2000V (300 / 500V) voltage experiments for 5 minutes without breakdown.
Task temperature: The low temperature for normal tasks does not exceed 70 ° C, the low temperature for BVR-105 tasks is 105 ° C, and the laying temperature of wires should not be lower than 0 ° C;
Allowable bending radius: The outer diameter (D) of the wire is less than 25mm, not less than 4D; the outer diameter (D) of the wire is 25mm or more, not less than 6 (D).
This product is suitable for fixed installation of power installation with AC additional voltage 450 / 750V and below. Such as home improvement lighting. Fixed wiring can be used in indoor open laying, pipe wearing and other places. In order to facilitate the difference in the device process, it can be divided into seven colors: red, yellow, blue, green, black, white, and double. Because BVR is soft structure, its application range is mostly in soft environment. The difference between BVR wires and BV wires is that the conductor diameter of the R-type wire is soft copper wire. That is: add the number of conductors, increase the diameter of a single conductor, the diameter of a single conductor is less than 1 mm. In this way, the BVR wire is very soft, and the laying angle requirements are greatly reduced compared to the BV wire. It is more convenient and fast to thread the pipe and the trunking, which reduces the task intensity and greatly improves the task efficiency.
Also, BVR wires are divided into flame-retardant wires (ZR-BVR), fire-resistant wires (NH-BVR), and low-smoke halogen-free wires (WDZ-BVR) according to the materials used. The user has a sensitive grasp based on the place of use. Among them, low-smoke-free (low) halogen wires have a great deal of smoke when the flame is extinguished. The released gas does not contain halogen (low-halogen) elements and is non-toxic (low-toxic). When a fire breaks out, it can greatly increase the harm to instruments, equipment and human bodies. Therefore, it is widely used in high-rise construction, hospitals, large libraries, stadiums, disaster prevention and control buildings, stations and civil airports, passenger waiting rooms, cultural relics maintenance. Places and subways, underground malls or densely populated public places ...
The difference between BV and BVR:
(1) From the perspective of consumer technology, BV is single-core and BVR is multi-core. In manufacturing, BVR is a bit more complicated than BV.
(2) In terms of price, BV and BVR are more expensive than BV because they are only in process. According to the rules of domestic and foreign electrical commissioners, the range of BVR is from 2.5 mm to 70 mm, but according to the needs of China's practice, it is the same as BV.
(3) In terms of function, BV and BVR are basically opposite, and BVR is slightly heavier in terms of component.
Color: red, yellow, blue, green, black, brown, yellow-green, white, etc., can be customized according to requirements;
Uses: Applicable to AC extra voltage 450 / 750V and below power, household electrical appliances, instruments and telecommunications equipment and other lines, and more commonly used in various machinery and equipment, strong flexibility.
