ZR-VV copper core flame retardant power cable

Introduction of ZR-VV technical parameters of low voltage 0.6/1KV copper core flame retardant power cable

Product name / application voltage

ZR-VV: copper core flame retardant PVC insulated and sheathed power cable

Applied voltage: 0.6/1KV

Main raw material: copper core, flame retardant PVC insulation, PVC sheath

Two, product implementation standards

The cable design conforms to the national standard "GB/T 12706.1-2008_ first part: rated voltage of 1kV (Um=1.2kV) to 3kV (Um=3.6kV) cable" and the International Electrotechnical Commission recommended IEC60502 standard requirements, the implementation of national standards "GB/T flame retardant properties of 19666-2005 flame retardant and fire resistant cable general".

Three, the use of products, the use of characteristics

Use, the use of ZR-VV flame retardant cable characteristics, product structure and VV is basically the same, except that the flame retardant performance, the safety performance is high, can be used in high-rise buildings, more densely populated places, such as stations, shopping malls etc.. VV-0.6/1KV copper core PVC insulated and sheathed power cable with reference to my company website.

Flame retardant cable refers to the specified test conditions, the specimen is burning, the flame source is removed, the flame spread only in a limited range, remnant spark or burning in a limited period of time self extinguishing cable. Its basic feature is: in case of fire may burn out and can not run, but can prevent the spread of fire. In layman's terms, the cable in case of fire, can be limited to the local range of combustion, not to spread, to keep the other equipment, to avoid causing a greater loss.

According to the "Regulations" test method of cable burning, the flame retardant cable bundle combustion test method of the assessment is divided into A, B, C3 class, which is a class a cable the severe test condition, B, C class performance is better, the price is the most expensive. The structure, characteristics and selection of flame retardant cable and fire resistant cable released on the website of our company are detailed.

Four, technical parameters:

Because the flame retardant cable is used to resist the fuel insulation layer, the outer diameter is more common in the same model specifications increased by 3 ~ 5mm.

Technical parameters can refer to the company's website released the "VV-0.6/1KV copper core PVC insulated and sheathed power cables" above the data is for reference. There are many factors affecting the concrete laying, such as the time of use, the length of the laying, the heat dissipation condition, the influence of the laying mode and the temperature of the environment.
