Polymer-Housed Lightning Arresters

The polymer-housed lightning arresters feature a polymer and composite material housing, with a single-column or multi-column resistor disc column as the core. They cover voltage ratings from 10kV-1000kV AC and ±0.75kV-±1100kV DC.

Porcelain-housed Lightning Arrester

The porcelain-housed lightning arrester uses a porcelain bushing as the external insulation, with a single-column or multi-column resistor disc column as the core, featuring an independently sealed gas space, with voltage levels covering 10kV-1,000kV AC.

GIS Tank-Type Lightning Arresters

GIS tank-type lightning arresters employ a metal-enclosed housing with SF6 gas as the internal insulation medium. They utilize single-column or multi-column resistor disc columns in parallel as the core, covering AC voltage ratings from 110kV-500kV.

Lightning Arrester for DC Circuit Breakers

The Company has developed a ±500kV lightning arrester for DC circuit breakers, used to limit the breaking overvoltage in DC systems and absorb the energy stored in inductive components during system short circuits.

Pluggable Lightning Arresters

Shielded plug-in surge arresters are suitable for C-GIS switchgear, gas-insulated ring-main units, and oil-immersed transformer protection in power systems up to 35kV. The external design uses a fully shielded metal housing, while the internal components utilize imported liquid silicone rubber material.

EMU Lightning Arrester

The high-speed railway uses a gapless metal oxide lightning arrester, primarily applied in high-speed railway systems. The high-speed rail lightning arrester exhibits excellent nonlinear volt-ampere characteristics, presenting a high-resistance insulation state under normal operating voltage. When subjected to lightning or switching overvoltage surges, it enters a low-resistance state, rapidly discharging surge currents into the ground, protecting parallel electrical equipment from damage and ensuring insulation safety.

Converter Valve Lightning Arrester

The converter valve is the core equipment of the UHV converter station, realizing AC-DC conversion. The valve lightning arrester is connected in parallel at both ends of the converter valve to protect it from overvoltage damage.

Controllable Self-recovering Energy Dissipation Device with Lightning Arrester

Our company has developed an AC controllable self-recovering energy dissipation device equipped with a lightning arrester. This device utilizes mechanical switches to control the protection characteristics of the lightning arrester, enabling controlled suppression of fault ride-through overvoltage and enhancing the stability of DC systems.
