■110KV~220KV高压交联电缆的使用特性Specific property for usage of 110KV~220KV XLPE high-voltage cable

1.电缆导体长期允许最高工作温度为90℃，应急过载最高工作温度为130℃，短路时（时间≤5秒）导体最高温度为250℃。

Cable’s conductor highest working temperature is allowed up to 90℃, and overload when meet an emergency is 130℃,When short circuit (in ≤5 seconds) the highest temperature is 250℃

2.电缆安装敷设时的环境温度应不低于-20以下敷设，应对电缆预热。

When installing or laying cable, the ambient temperature should be less than -20℃, and have to give a preheat to cable.

3.电缆最小弯曲半径：

The minimum bending diameter:

注：表中D0为电缆外径实测值。

Note: In form, D0 is a real test value to cable’s outer diameter.

4.电缆安装时的轴向最大允许牵引力（未考虑转弯处的径向侧压力）T=K×芯数×截面（kg），式中系数K值，铜芯取7，

铝芯取4。

Allowed biggest axial traction force to outer diameter when laying cable (not consider the radial lateral-pressure at bent set ion) T=K×core NO. ×section (kg), in formula, the coefficient K value should be: the copper core get 7, the aluminum core get 4. 5.电缆弯曲时的允许最大侧压力P

单芯电缆要求P≤500kg/m. P=T/R(T为轴向牵引力，R为弯曲轮半径)，由上式可知，因牵引力一般由电缆长度和重量决定，要使P符合上述要求，应加大转弯轮直径。

Allowed biggest lateral-press P, when cable is being bent

The single core cable is required P≤500kg/m.

P=T/R (T is indicated axial traction force; R is indicated radius of bent-wheel), Knowing from above formula, as the traction force is made up by length and weight of cable. So it lets P to applying requirement as above. Then the diameter of bent-wheel should be widened.

6.电缆敷设不受落差限制。

Cable laying is not being restricted by drop.
