Flame-retardant Cables: ibec60332-3 / bs4066-3 flame-retardant grades (BunchedWires or Cables vertical Flame On BunchedWires/Cables) this is a beam cable. According to the test regulations, the 3.5m long cable samples are fixed with iron wire on the trapezoid frame, and the number of samples is determined according to the non-metallic materials required for different classification. The sample is hung vertically on the back wall of the furnace and air is introduced into the furnace through the inlet on the bottom plate. At 750 ℃ flame propane plane and the sample, the sample in the compulsory blowing (5 m3 / min air emissions, wind speed 0.9 m/s), must be in vertical combustion is not up to 20 minutes, cable within 2.5 meters flame spread out on its own. IEC60332 is divided into A, B, C and D to evaluate the flame retardant performance.

In order to meet the needs of the market, our factory has developed shielding and flame-retardant control cables in recent years on the basis of producing ordinary plastic insulation control cables.

PC级双电源切换开关：能够接通和承载，但不用于分断短路电流或过载电流，画图时一般如下，内部可以画成两个隔离开关（也有画成负荷开关的），PC级断路器前端一般加保护电器，如断路器、熔断器、带熔断器的负荷开关等等，但对于消防类负载因为要去不能断电，所以只能加单磁型断路器（仅短路保护）或负荷开关和隔离开关，其他非消防类负载保护电器可以随意加，且应配合火灾强切电源。PC级因为无分断能力，所以所有的分断都是靠上级的保护电器，当前级失电，自动转换到另一路，不管是因为过载还是因为短路，只要上级保护电器断开失电，都会自动切换到另一个回路上。
