XLPE电缆是电力系统中主要的输送电设备。局部放电是造成电力电缆绝缘层破坏的主要原因。
XLPE cable is the primary transportation equipment in electric power system and Partial discharge (PD) is the main cause which destroy electric power's cable insulated layer.
通常电缆的绝缘层在数小时甚至数天之后才能恢复其防水能力。
Typically, the insulation will regain its ability to block water hours, or even days, later.
太阳能连接软管可以简便地从温度传感器连接到控制器，他除了软管和绝缘层外，还附加了一个电缆。
Also to ease making the connection from collector temperature sensor to control unit, a double-tipped silicon cable is attached besides the hose and insulation.
电缆的绝缘层必须够强韧，才能抵挡这样的脉冲。
The cables will need insulation strong enough to contain this spike.
绝缘层一般为纯天然橡胶，铜丝为无氧铜，这样，才能保证线芯的良好导电性及电缆的安全性。
The insulating layer is pure natural rubber, copper wire for copper, so, in order to ensure the safety of wire and cable of good conductivity.
用导电或半导电层把电缆的电场封闭在包围着导线的绝缘层中。
Use of conductive or semiconductive layer of the cable electric closed in around the wire insulation layer.
隔离绝缘层和外护层以及内衬层，以防它们之间相互粘结而影响电缆的机械、物理、电性能等。
To separate the insulation, sheath and inner covering, and keep them from bonding and affecting the mechanical, physical and electrical properties of the cable.
包括具有优异的机械和电性能，且为环境有利的多相聚合物组合 物的用于电缆的绝缘层。
Insulation layer for cables comprising a heterophasic polymer composition having superior mechanical and electrical properties and being environmentally friendly.
当电缆遭到燃烧时，能够吸收大量的热量，并形成碳化层，隔绝气层、保护绝缘层免受燃烧，使火灾的损失不致于进一步扩大化。
When the cable was burning, a lot of heat can be absorbed, and form a carbon layer to isolate the gas and protect the insulation layer from burning, so that the loss will be cut.
绝缘层的突变（指电缆端部）引起非常大的集中的电应力（电场强度），这可通过电缆穿出地面时采用昂贵的称为“电缆头”的端部来消除。
Abrupt insulation changes cause very large concentrated electrical stresses. These stresses can be eliminated by terminating the cable above ground in an expensive device known as pothead "."
