The protection of the power grid is closely related to our working life, and effective power grid protection can reduce the power outage caused by accidents, which also means a significant reduction in maintenance costs and maintenance time, thus reducing the loss of economic property caused by power outages such as industry.

When it comes to power grid protection, of course, the heat shrinkable pipe can not be separated, because the main function of the Heat shrinkable pipe is the electrical insulation of the connector, Welding point anti-rust and anti-corrosion, mechanical protection and wire harness protection.

The common heat shrinkable pipe power grid protection in our life has the protection of relays, the insulation protection of generators, the insulation protection of distribution cabinets and switchgear, etc.

During the failure of the power grid, distributed energy should remain operational and connected to the power grid, and the power grid voltage stability should be guaranteed by feed-in power. Insulation protection of electric power can avoid electrical damage or mechanical damage to distributed energy in the event of failure. If the accident occurs, should avoid minimizing the loss, the use of insulation protection of the heat shrinkable pipe should be halogen-free, low smoke flame retardant, so environmental protection and flame retardant standards for the protection of the power grid is very important.

The heat shrinkable tubes used in power grid protection require halogen-free environmental protection and achieve the highest flame retardant grade: VW-1 level.

电网防护中热缩管的使用

电网的防护对我们的工作生活息息相关，有效的电网防护可以减少事故引起的停电现象，这也意味着大大减少维修费用与维修时间，从而减少工业等停电期间所带来的经济财产损失。

提到电网防护那当然离不开热缩管，因为热缩管的主要功能就是连接件的电绝缘、焊点防锈防腐、机械防护和线束防护等。

我们生活中常见的热缩管电网防护有继电器的防护，发电机的绝缘防护，配电柜、开关柜的绝缘防护等。

在电网发生故障期间，分布式能源应保持运转并连至电网，通过馈入无功率以保证电网电压稳定。电力的绝缘防护可避免发生故障时对分布式能源造成电气损伤或机械损伤。如果事故一旦发生，应当避免损失最小化，所采用绝缘防护的热缩管应当无卤无害，低烟阻燃，所以环保与阻燃标准对于电网的防护非常重要。

电网防护中使用到的热缩管需要无卤环保，并达到最高的阻燃等级：VW-1级别。
