一、產品特點及用途
聚氯乙烯和護套控制電纜適用於交流額定電壓Uo/U為450/750V及以下控制、監控回路及保護線路等場合，作為電氣裝備之間的控制接線。
阻燃控制電纜的主要特點是電纜不易著火或著火時延燃僅局限在一定范圍內，適用於對阻燃性能要求較高的場合。
耐火控制電纜的主要特點是電纜除瞭能在正常的工作條件下傳輸電力外，電纜在著火燃燒時仍能保持一定時間的正常運行，適用於對耐火特性有要求的場合。
二、產品標準
本產品按GB 9330—1988標準組織生產，還可按用戶要求的其它標準生產。
阻燃型電纜除按上述標準外，其阻燃性能按GB/T 18380.3-2001標準規定分成A、B、C三種不同的阻燃類別，A級類別的阻燃性能最優，用戶可根據需要選用。

1. Characteristics and Applications of the products
PVC insulated PVC sheathed control cable is used to connect electrical equipments. It applies to controlling, monitoring and protective system with A.C. rated voltage Uo/U up to and including 450/750 volts.
The main features of the flame retardant PVC control cable is hard to get fire or that the continuous burning of cable is very limited when it is on fire. It applies to the places with special demands of flame retardant property.
Fire-resistance cable can operate normally for some time when it is burning except that it can transmit electrical power under normal condition. It is used in the places necessary to resist fire.
The main characteristics of low smoke, low halogen, flame retardant control cable is low smoke emission and low release of HCL gas besides the property of flame retardant. It can be used in the places with special demands of the density of smoke emission and the release of HCL gas besides the property of flame retardant. It can be used in the places with special demands of the density of smoke emission and the release value of HCL gas when cable gets burning.
2. Standards of the products
The cable is manufactured in accordance with the standards of GB 9330-1988. It can also be produced according to special requirements put forward by clients.
Besides the standards mentioned above, the flame retardant property of the flame retardant cable must meet the corresponding demands of class A, B or C which is stipulated in GB/T 18380.3-2001 Amongst the 3 class, class A is best, while C worst. Clients can selec any type of cable as practical needs.
Fire resistance property of the fire resistance cable can be GB/T 19216.21-2003.
3. Type
Type of the common cable:
KVV-copper conductor PVC insulated PVC sheathed control cable
