TPS1 is air insulated switchgear for up to 24kV secondary distribution network.

It is suitable for a lot of applications, like compact transformer substations, airport, industrial & mineral enterpriseand residence area, etc.


TPS2 is highly space efficient MV switchgear with 550mm wide panel.

It is air insulated equipped with vacuum load switch and vacuum circuitbreaker for most of switching application.


TPS6 Gas insulated is medium voltage switchgear for secondary distribution network.

It can be used as RMU for open ring network which offers a choice of either a switch-fuse combination or vacuum circuit breaker with relay for protection of the transformer. TPS6 is a completely sealed system.


TPS7 Green RMU is a new generation of environment-friendly type of switchgear developed exclusively by Hezong Science & Technology.

By adopting epoxy resin and dry air as insulating medium instead of SF6 gas or oil, TPS7 can provide customers utmost safety without any gas leakage hazard.


TPS8 is metal enclosed solid-insulated switchgear. Since it is SF6 –free, it eliminates the risk of gas leakage, thereby reducing effect on environment.

The main circuits are fully sealed in epoxy resin and main busbar and cable accessories are also fully insulated by silicone, thus ensuring stable performance and safe operation.


KYN28 is air insulated medium voltage metal-clad switchgear suitable for indoor installations. It has a wide range of applications in primary distribution network, such as utilities, power plant industries, marine sectors, transport and services.

It is designed to meet the most demanding international standards for safety, reliability and performance.
