- High Voltage Electrical Switchgear is intended for control, protection, and electrical isolation in power systems rated 35kV and above.
- It is mainly based on air-insulated switchgear construction and suits 35kV/110kV outdoor substations, power-plant step-up stations, and conventional high-voltage distribution projects.
- The supplied product information identifies AIS as a lower-cost alternative to GIS where the site can provide the required air-insulation clearances.

Switching Functions:
- The equipment range primarily includes circuit breakers, disconnectors, and earthing switches.
- These components cover circuit control, isolation, and grounding tasks within the high-voltage side of a substation.
- Rated current is 630–3150A, with confirmed short-circuit breaking capacity of 25–40kA.
Maintenance-Oriented Layout:
- Air is the main insulating medium, so the equipment arrangement and functional components remain comparatively visible for inspection.
- Standardized switching components make it easier to identify the relevant functional part when maintenance is required.
- Site layout should provide the spacing needed by the air-insulated arrangement before the equipment scheme is finalized.
Technical Scheme Definition:
- Rated voltage, current, breaking capacity, switch combination, and project drawings can be used to define a customized configuration.
- OEM/ODM cooperation is supported after completion of the required authorization.
- Buyers sourcing High Voltage Electrical Switchgear should confirm the exact switching equipment combination rather than relying only on voltage and current ratings.
Factory Release and Commercial Details:
- Materials and components are checked at incoming inspection, followed by process inspections during manufacturing and finished electrical performance testing.
- 100% electrical performance testing is completed before packing, and purchaser-arranged third-party inspection is supported.
- High-voltage equipment receives rust-prevention and transport reinforcement according to its structure; export units use solid-wood cases.
- Customized production is generally 20–35 working days based on drawings and technical requirements.
- EXW and FOB terms are available. Ordering information should include system voltage, rated current, breaking capacity, required switch combination, installation site, quantity, and project requirements.
