XLPE insulated control cables are suitable for the electrical apparatus and instruments, signal transmission of distribution devices and control and measure system with A.C rated voltage of 450/750V and below, used by metallurgical, power and petrochemical industries etc.

XLPE insulated control cables; it can avoid fire accidents occurring and losses reducing that this products can prevent fire spreading on the circuits.

XLPE insulated control cables, the characteristic of this product is that it can ensure the normal operation of the cables in some period, when it burning. It offers time for crowd evacuation and equipments rescue.

XLPE insulated control cables with the characteristic of low-smoke and flame-retardant are suitable for the electrical apparatus and instruments, signal transmission of distribution devices and control and

KYJVP2 14*2.5控制電纜使用特點：

1、 額定電壓Rated voltage

電纜額定電壓U0/U是450/750V

Rated Voltage of cable U0/U is 450/750V

2、 導體額定工作溫度

電纜導體的zui高額定工作溫度為90℃。

短路時（zui長持續時間不超過5s）電纜導體的zui高溫度不超過250℃。

The rated temperature of conductor

The maximum temperature of the cable conductor is 90℃.

During having a short circuit, （lasting less than 5s）, the maximum temperature of the cable conductor must be below 250℃.

3、 敷設環境溫度

電纜敷設時的環境溫度應不低于0℃，否則需要事先預熱。

Ambient temperature for laying

the ambient temperature for laying shall be above 0℃, if not the cable need be preheated.

4、 安裝彎曲半徑

a） 無鎧裝層的電纜，應不小于電纜外徑的6倍；

b） 有鎧裝或銅帶屏蔽結構的電纜，應不小于電纜外徑的12倍；

c） 有屏蔽層結構的軟電纜，應不小于電纜外徑的6倍。
