HVX40.5-K

HVX 40.5/K Product Characteristics

40.5 kV Voltage Rating: Suitable for 40.5 kV AC power distribution systems, applicable to substations, industrial enterprises, energy and infrastructure projects.

Vacuum Arc Extinguishing Technology: Employs a vacuum arc-extinguishing chamber for current interruption, featuring rapid arc extinguishing, strong dielectric recovery capability, and minimal contact wear.

High Short-Circuit Breaking Capacity: Reliably interrupts short-circuit fault currents in the system, improving the safety and reliability of the power distribution network; actual breaking parameters should be based on the specific model nameplate or technical datasheet.

High Insulation Level: Designed for the insulation requirements of 40.5 kV systems, it can withstand specified power frequency and lightning impulse voltages, suitable for higher voltage level power distribution applications.

Long Mechanical Life: Optimized operating mechanism combined with vacuum arc-extinguishing technology meets the requirements for long-term operation and repeated opening and closing operations.

Low Maintenance Design: The vacuum arc-extinguishing chamber adopts a sealed structure, eliminating the need for replenishing oil, SF₆, or other arc-extinguishing media, thus reducing daily maintenance work.

Reliable energy storage operating mechanism: Typically employs a spring energy storage mechanism, which can be configured with electric energy storage to achieve stable and rapid closing and opening operations.

Compact structural design: While meeting the requirements of 40.5 kV insulation distance and breaking capacity, the equipment structure is optimized for easy integration with medium-voltage switchgear.

Comprehensive safety interlocking: Can form mechanical and electrical interlocks with switchgear trolleys, grounding switches, cabinet doors, etc., reducing the risk of misoperation.

Flexible accessory configuration: Can be configured with shunt trip units, undervoltage trip units, closing coils, auxiliary contacts, electric energy storage mechanisms, and interlocking devices according to project requirements.

High operational reliability: Suitable for power systems and industrial power distribution applications with high requirements for power supply continuity and equipment reliability.

Wide application range: Can be used for the control and protection of circuits in transformers, feeders, busbars, power generation systems, and large industrial loads.
