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控制电缆使用特点：

1、 额定电压Rated voltage

电缆额定电压U0/U是450/750V

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

2、 导体额定工作温度

电缆导体的zui高额定工作温度为90℃。

短路时（zui长持续时间不超过5s）电缆导体的zui高温度不超过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、 敷设环境温度

电缆敷设时的环境温度应不低于0℃，否则需要事先预热。

Ambient temperature for laying

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

4、 安装弯曲半径

a） 无铠装层的电缆，应不小于电缆外径的6倍；

b） 有铠装或铜带屏蔽结构的电缆，应不小于电缆外径的12倍；

c） 有屏蔽层结构的软电缆，应不小于电缆外径的6倍。

The bend radius

a） For unarmoured cable, it shall not be less than 6 times of the external diameter of cable

b） For armoured cable or copper tape screened cable, it shall not be less than 12 times of the external diameter of cable

c） For the flexible cable with screen layers, it shall not be less than 6 times of the external diameter of cable
