A, product M called/applicable voltage

Zr-vv: copper conductor flame retardant PVC J-edge PVC sheathed power cable

Applicable voltage: 0.6/1kV

Main raw materials: copper core, flame retardant PVCJ edge, PVC sheath

Ii. Product execution standards

Cable design conforms to the standard GB/T 12706.1-2008_D1 part: Rated voltage 1kV(Um=1.2kV) to 3kV(Um=3.6kV) cable and IEC60502 recommended standard, flame retardant performance implementation standard GB/T 19666-2005 flame retardant and fire resistant wire and Cable general Rules.

Three, product use, use characteristics

Flame retardant cable ZR-VV uses, use characteristics, product structure is basically the same as VV, the difference lies in its flame retardant performance, in the rest of the performance is relatively high, can be applied to high-rise buildings, densely populated places, such as stations, shopping malls, etc.. Please refer to "VV-0.6/1kV copper core PVC J-edge PVC sheathed power cable" published on our website.

Flame retardant cable refers to the cable that the sample is burned under specified test conditions and the flame spread is only within a limited range after the test fire source is removed, and the residual flame or residual burning can be extinguished by itself within a limited time. Its basic characteristics are: in the case of fire may be burned out and can not operate, but can prevent the spread of fire. Generally speaking, a fire cable W, can limit the combustion in a local range, do not produce spread, keep other kinds of equipment, avoid causing greater losses.

According to the provisions of "Wire and Cable Combustion Test Method", the flame-retardant cables examined by the bunching combustion test method are divided into A, B and C3 classes. The test conditions of A class cable are harsh, the performance is better than B and C class, and the price is also expensive. For details, please refer to the structure, characteristics and Selection of flame-retardant cables and fire-resistant cables published on our website.

Four, technical parameters:

Since the flame-retardant cable is made of j-edge layer of resistance fuel, its outer diameter is generally increased by 3 ~ 5mm on the same model specifications.

The technical parameters can refer to the "VV-0.6/1kV copper core PVC J-edge PVC sheathed power cable" published on our website. The above data is for reference. There are many factors affecting the specific laying; Such as power consumption time, laying length, heat dissipation conditions, laying mode influence, environmental temperature, so need to be determined after comprehensive consideration by the user.
