THE HIGH VOLTAGE FUSE CUTOUT IS DISCONNECTED

IN THE POWER TRANSMISSION LINE

Optimize the transmission line, strengthen the maintenance of the transmission line, improve the immunity of the transmission line, can better improve the stability of the transmission line, and our composite insulators can better meet the needs of customers.

24kv Outdoor Expulsion Drop-out Type Fuse Cutout

Drop-out fuse is the most commonly used short-circuit protection switch for 10-38kV distribution line branch lines and distribution transformers. It has the characteristics of economy, easy operation, and strong adaptability to outdoor environments. It is widely used in 10-38kV distribution lines and power distribution. The primary side of the transformer is used for protection and equipment switching and switching operations.

165A Low Voltage Pole Mounted Circuit Breaker Adapted To Significant Load Imbalances

The protection and management of MV/LV transformers in rural areas requires the use of specific circuit breakers adapted tosignificant load imbalances, and thus guarantees complete power usage even in unbalanced conditions. These devices (4 poles, three of which are protected) use air-break technology with chambers with metal partitions to cut the arc. Low voltage pole mounted circuit breaker D165T - D265T with a digital trip unit.

33kv Silicone Rubber Composite Insulator for Support Cable

Insulators are widely used in overhead transmission lines to provide mechanical support and electrical protection, as well as in distribution lines and substations. Silicone rubber is the most widely used polymeric insulation material for high voltage insulators.HAIVO brand composite insulator made of silicone rubber.Depending on voltage considerations, different kinds of insulators are used in power systems,we have Pin insulator,strain insulator,suspension insulator.post insulator,long rod insulator,horizontal post insulator,Railway insulator,shackle insulator,stay insulator.

36kv High Voltage Surge Arrester for Distribution Line

Zinc oxide surge arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good non-linear volt-ampere characteristics of zinc oxide to make the current flowing through the surge arrester at normal working voltage very small (microamp or milliampere level); when the overvoltage acts, the resistance drops sharply, venting the overvoltage Energy to achieve the effect of protection. The difference between this kind of lightning arrester and the traditional lightning arrester is that it has no discharge gap, and uses the non-linear characteristics of zinc oxide to discharge and break.
