Selling Points and Advantages
1. Operational Safety
Through the following security measures, we can provide users with enhanced security protection:
1) Integrated three-position load switch: The circuit breaker replaces the isolating switch with a load switch, enhancing safety and reliability. The fully enclosed primary-side design provides protection against accidental contact, while the mechanically interlocked live indicator that meets the “five-protection” requirements can display whether the incoming and outgoing lines are energized, ensuring reliable operation.
2) Fully enclosed design: all 10 kV switchgear and busbar live parts are sealed within an air-insulated cabinet welded from 3 mm stainless steel plates.
3) Equipped with a silicone rubber cable plug to achieve complete insulation and sealing of the cable termination, thereby protecting the spring-operated energy-storage mechanism from external environmental factors such as dust, moisture, and small animals.
2. Cost-effectiveness
Maintenance-free; highly reliable; service life of up to 20 years; flexible design: multiple incoming cable configurations allow for various combinations—left, right, top, or front entry—and arbitrary interconnection among units. The use of insulated busbars enables both front-to-back and side-by-side cabinet configurations, offering exceptional design flexibility.
3. Wide range of applications
The feed-out lines offer high capacity and a small footprint, making them suitable for a wide range of applications.
