EV-EFPF充电桩电缆

(a) heat-resistant wire and cable

耐热材料的电线电缆是绝缘和护套材料本体树脂具有耐热性能，主要品种有：聚氨脂（可达155℃级）、聚脂（可达135℃）、聚偏氟乙烯（150℃）和尼龙（可达115℃）的绝缘或护套材料。常用于通信、汽车、电机、建筑等行业。

Wire and cable material is heat insulation and sheath material body resin with heat resistance, the main varieties are: polyurethane (up to 155 DEG C grade), polyester (up to 135 DEG C), polyvinylidene fluoride (150 DEG C) and nylon (up to 115 DEG C) insulation or sheath material. Commonly used in communicati***, automotive, electrical, c***truction and other industries.

（二）普通电缆材料通过各种方式的改性而达到耐热性：

(two) the heat resistance of ordinary cable material is improved by various means:

1、橡胶材料的耐热改性

1, heat resistance modification of rubber materials

橡胶材料因其耐热性差，因而提高工作温度的余度较小，普通橡胶填加较多热稳定剂和经交联处理才能达到90℃，因而不能称为耐热电缆，如丁苯橡胶、氯丁橡胶、氯磺化聚乙烯等。主要应用于橡胶绝缘移动用软电线、橡胶绝缘软电力电缆和控制电缆等。

Rubber materials because of its poor heat resistance, thus increasing the working temperature of the redundancy is ***all, ordinary rubber filled with more heat stabilizer and crosslinked can reach 90 DEG C, which can be called a heat-resistant cable, such as styrene butadiene rubber, chloroprene rubber, chlorosulfonated polyethylene etc.. The utility model is mainly used for rubber insulated flexible wire, rubber insulated soft power cable and control cable.

但三元乙丙橡胶可经改性，使耐温等级提高到135℃，加上具有较好的绝缘性能，因而在橡胶方面具有较好的发展前景。

But three ethylene propylene diene rubber can be modified, so that the temperature rise to 135 degrees C, with good insulation performance, and thus has good prospects for development in rubber.

2、聚***电缆的改性

2, PVC cable modification

普通聚***电缆的工作温度为70℃，聚***电缆料的高可混性，使其改性成为可能，多量的热稳定剂的使用，可便PVC的耐热从70℃上升到90℃或105℃，因而大大扩大了PVC这种老式材料的适用性，也许这就是PVC电缆长盛不衰的原因之一吧？EV-EFPF充电桩电缆

Ordinary PVC cable working temperature of 70 DEG C, PVC cable material highly mixed, the modification is possible, the use of large amounts of heat stabilizer, PVC can heat up from 70 C to 90 C and 105 C, and the applicability of PVC to the old materials greatly expand, perhaps this is PVC cable has one of the reas***?

90℃PVC电缆料常用于交联聚乙烯电缆护套，主要用于电力、控制和电气装备线缆，由于PVC的改性，使本可淘汰的PVC电缆料在护套的使用上将会延续相当长的时间。

90 C PVC cable material commonly used in XLPE cable sheath, mainly used in electric power, control and electrical equipment cable, due to the modification of PVC, the elimination of PVC cable material on using the jacket will continue for a long time.

聚******复合物的主要成分是PVC，因而与聚******复合物电缆与PVC绝缘电缆具有相同的改性性能。EV-EFPF充电桩电缆

The main component of PVC nitrile composite is PVC, so it has the same modification performance as the PVC cable.

3、聚乙烯电缆的改性

3, polyethylene cable modification

聚乙烯材料的塑性较好，但可填充性较差，因而不能填加热稳定剂方法提高耐热温度。聚乙烯电缆可通过DCP干法化学交联和***温水交联将工作温度提高到90℃，前者用于中高压电力电缆，后者用于低压电缆。

The polyethylene material has good plasticity, but the filling property is poor, so it can not be filled with heating stabilizer to improve heat resistance. Polyethylene cable can be increased to 90 DEG C by DCP dry chemical crosslinking and silane warm water crosslinking. The former is used for medium and high voltage power cable, the latter is used for low voltage cable.

但另一种交联方式--辐照交联改性，则可将聚烯烃（主要是聚乙烯）的工作温度大幅度提高，经辐照的绝缘料可按条件不同，耐温可达到105℃、125℃、135℃、150℃，国外则有能提高到180℃。主要是通过高能电子转化成稳定的键能，使其分子结构对热稳定性加强，同时配以适当的热稳定剂，根据能级大小和热稳定剂的效能，分为不同耐热等级。EV-EFPF充电桩电缆

But another way of crosslinking radiation crosslinking modified, can be polyolefin (mainly polyethylene) the working temperature is greatly improved, the insulation material irradiated according to different conditi***, temperature resistance can be reached 105 C, 125 C, 135 C and 150 C, while abroad can be improved to 180 DEG C. Is converted into stable bond energy by electron, the molecular structure to strengthen the thermal stability, at the same time with the appropriate heat stabilizer, according to the size and level of heat stabilizer effectiveness, divided into different level of heat.

辐照交联工业常用加工设备为电子***，是将电子束高压增

The commonly used processing equipment for irradiation crosslinking is an electron accelerator
