Products Description
Solid-insulated switchgear (SDS)
Solid-insulated switchgear (SDS), also known as solid-insulated switchgear, is a medium-voltage power distribution solution that completely encapsulates conductive components in epoxy resin insulating materials.
Unlike traditional air-insulated or sulfur hexafluoride (SF6) gas-insulated switchgear, SDS eliminates exposed conductors and provides higher safety and environmental friendliness for modern power networks.

Excellent safety and environmental protection: By completely wrapping the conductive parts in a solid insulating material, SDS minimizes the risk of electric shock and the hidden dangers of interphase short circuits. Its SFP-free design complies with global environmental regulations, can reduce greenhouse gas emissions, and contribute to sustainable infrastructure construction.
Compact structure and low maintenance requirements: Solid insulation technology makes the equipment structure more compact-the volume of the air-insulated switchgear of the same voltage level can be reduced by up to 30%. The material has dust-resistant, moisture-proof, and pollution-resistant characteristics, and does not require routine cleaning or gas replenishment, effectively reducing the whole life cycle cost and operating downtime.
High reliability and intelligent integration capabilities: equipped with a vacuum interrupter, SDS has stable breaking performance and long service life. It is compatible with intelligent monitoring systems, supports remote diagnosis and automatic fault isolation, and is an ideal choice for smart grid applications.
Applicable environmental conditions
The solution takes into account performance, safety and sustainability, and is the preferred solution for utility and industry customers to pursue long-term efficient operation.
Electrical parameters
Suitable for 7.2kV–38kV systems, the rated current can reach up to 1250A, and the short–circuit breaking capacity is 20kA-25kA, which can be customized according to project requirements.
Environmental adaptability
Can adapt to a variety of harsh environments-resistant to salt spray (coastal areas), industrial dust, high humidity and extreme temperatures (-40°C to +50°C).It complies with the IP67 protection level standard to ensure the reliable operation of indoor substations and outdoor installations (including urban underground power distribution rooms and renewable energy power stations).
