Grid protection is closely related to our working life, effective grid protection can reduce the phenomenon of power outages caused by accidents, which also means to greatly reduce maintenance costs and maintenance time, thereby reducing the economic property losses caused by industrial and other power outages.

When it comes to grid protection, of course, it is inseparable from the heat shrink tube, because the main function of the heat shrink tube is the electrical insulation of the connection parts, the welding point anti-rust corrosion, mechanical protection and harness protection.

The usual heat shrink tube grid protection in our life has relay protection, generator insulation protection, power distribution cabinet, switch cabinet insulation protection, etc.

During the failure of the power grid, distributed energy should be kept running and connected to the grid, by feeding no power to ensure grid voltage stability. The insulation of electricity avoids electrical or mechanical damage to distributed energy in the event of a failure. If an accident occurs, the loss should be avoided to minimize, the insulation-protected heat shrink tube should be halogen-free, low smoke flame retardant, so environmental protection and flame retardant standards for the protection of the grid is very important.

The heat shrink tubes used in grid protection require a halogen-free environment and achieve the highest flame retardant rating: VW-1.

热缩管在电网防护中的使用
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。
