Product Introduction

Product Features

  1. Safe and Reliable

High-voltage live components such as switches and busbars are sealed within a gas tank welded from 3mm/304 stainless steel, using laser welding technology to eliminate gas leakage, with a service life exceeding 30 years.

Cable connectors are fully insulated and touch-safe, ensuring no risk of electric shock for operation and maintenance personnel.

Equipped with a comprehensive mechanical and electrical interlocking system to effectively prevent misoperation.

  1. Strong Environmental Adaptability

All live parts adopt a fully insulated and fully sealed design, making the product unaffected by harsh environmental conditions, with insulation performance unaffected by altitude.

  1. Modular and Flexible Expansion

Modules are connected via extended busbars, enabling fully modular configurations to meet various complex power distribution schemes.

  1. Maintenance-free

The fully sealed structure and high protection rating ensure the product is unaffected by environmental conditions, requiring no cleaning or maintenance. Its robust structure and excellent mechanical and electrical performance guarantee high reliability and durability.

  1. Comprehensive Product Series

Offers multiple configurations, including load switches, load switch + fuse combination devices, and circuit breakers, with flexible combinations suitable for various power distribution scenarios.
