What Is BVR Cable And BV Cable?

Bvr wires and rvv cables are all multi-core cables with good flexibility. What is the difference between bvr and rvv?

One: what is bvr wire

Bvr wire is a special type of flexible wire for distribution box, also known as secondary wire. Use the insulating layer soft wire of the cable copper wire polybutadiene, which is used to fix the fixed wiring and specify the soft place. By the majority of welders and architectural decoration design staff like.

Two: what is rvv cable

The full name of rvv line is cable copper wire PVC insulated flexible wire, alias sheathed wire, electronic wire, power wire, multi-core wire, etc. Applicable to mobile laying soft places with rated AC current of 300/500V and below, used for power plugs, control lines and data signal coaxial cables of household appliances, instruments and electronic products and automation devices. Anti-theft alarm system and building intercom system suitable for specific occasions.

Three: the difference between bvr wire and rvv cable

1. Differences in English letters

rvv: r stands for copper wire, v stands for insulating layer polybutadiene

bvr: b is cloth wire, v is polyethylene, r is soft

2. Working voltage difference

rvv: rated cable 300V/500V

bvr: The rated voltage is 450/750V, the cable is soaked for 1 hour, and it can withstand the test of AC 50Hz, 2500V (450/750V), and 2000V working standard voltage for 5 minutes without passing through.

3. Working temperature difference

rvv cable: minus 10℃ to plus 70℃.

Bvr wire: the working temperature should not exceed 70 ℃, the working temperature of BVR-105 type is 105 ℃, and the temperature of the wire laying environment should not be less than 0 ℃.

4. Differences in applications

rvv cable: suitable for power plugs, control lines and data signal coaxial cables for household appliances, instruments, electronic products and automation devices, and is actually suitable for anti-theft alarm systems, building intercom systems, etc. It is mainly used in soft places such as medium and light mobile household appliances, instrumentation equipment, electrical products, and power lighting. It can transmit control data signals and switching power data signals, and is also suitable for laying in cable trays and plastic hoses.

bvr wire: special flexible cable for power distribution cabinet is used to fix the most flexible field in the fixed line. It is suitable for communication with the driving force of AC rated voltage of 450/750V and below, daily high-power electrical appliances, instrumentation equipment, communication equipment, etc. It is suitable for various mechanical equipment and has strong coordination ability.
