Product Introduction:

The Primary and Secondary Integrated Pole-Mounted Circuit Breaker (ZW20 type) utilizes vacuum arc extinguishing and SF6 gas as the insulating medium, designed for breaking and closing load currents, overload currents, and short-circuit currents. The three-phase vacuum interrupter of this circuit breaker is housed within a metal enclosure, and the operating mechanism has been miniaturized and optimized for performance, resulting in a compact three-phase common tank design. Independently developed and manufactured by Qingdao Topscomm Communication Co., Ltd., it fully complies with the Southern Power Grid's standardized design and grid connection requirements for integrated primary and secondary equipment, facilitating unified procurement and mass production by the Southern Power Grid.

Product Features:

1. Standardization

Complies with the Southern Power Grid's standardized customization requirements for integrated primary and secondary systems, with consistent installation dimensions and unified interfaces, allowing for interchangeability.

2. High Protection

Capable of accurately identifying and swiftly isolating short-circuit faults, ground faults, and broken wire faults.

3. Safety and Control

The equipment's development and production involve independent and secure material selection, achieving a 100% localization rate for secondary component parts.
