Overview
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.
Features
Excellent Residual Voltage Protection Level
It can effectively limit the amplitude of overvoltage and restrict the amplitude of overvoltage to a safe level through its internal nonlinear resistance elements, protecting subsequent equipment from high voltage damage.
High Energy Absorption Capacity
It can withstand large current impacts and energy releases in a short time, ensuring the stability and safety of the system.
Long-term Stable and Reliable Operation
After rigorous design and testing, it can maintain stable performance under various harsh environments and has a long service life.
Compact Structure and Small Footprint
A compact structural design is adopted to minimize the footprint, facilitating installation and improving system integration and operational efficiency.

Design Solution of 24kV Dry Air Insulated Ring Main UnitThe combination of Solid Insulation Assist + Dry Air Insulation represents the development direction for 24kV RMUs. By balancing insulation requirements with compactness and employing solid auxiliary insulation, insulation tests can be passed without significantly increasing phase-to-phase and phase-to-ground dimensions. Encapsulating the pole column solidifies the insulation for the vacuum interrupter and its connecting conductors.Maintaining the 24kV outgoing busbar phase spacing at 110mm,16/08-2025 -

Implementation Scheme for Installing Lightning Arresters or Voltage Transformers in Gas-Insulated Ring Main UnitsAccording to insulation type, ring main units (RMUs) can be categorized as gas-insulated or air-insulated. The former installs primary circuit components in a sealed metal enclosure filled with low-pressure gas (primarily SF₆ or mixed gases) as the insulating medium, using cable terminals for incoming and outgoing lines. Due to superior insulation, compact size, and modular design, they are widely used in 10kV outdoor distribution substations and prefabricated transformer stations. However, thei16/08-2025 -
