(April 2026, China) -At a time when the construction of power infrastructure has entered a stage of high-quality development, the stability and life-cycle value of equipment have received more and more attention. Kechang Electric's classic switchgear series, relying on more than 20 years of technical precipitation and market verification, with five core advantages of modular design, extreme environmental adaptation, long life, intelligent operation and maintenance, and green and low-carbon, continues to serve the power grid, new energy and industrial fields, and has become a long-term trusted "power gatekeeper" for many key projects.

Modular design, flexible adaptation to different needs
Kechang switchgear adopts modular design, and the cabinet body is made of 2.5mm thick aluminum-zinc coated steel plate, which is durable. Its drawer-type unit and fixed-type unit can be freely switched, the functional unit has a unified appearance and size, the spare parts are versatile, and the maintenance and replacement are convenient.With a multi-layer ventilation and heat dissipation system, the cabinet volume is only 1/3 of the traditional scheme. In areas with tight land resources such as urban substations, it has significant advantages. It can not only save land area, but also shorten the installation cycle by more than 60%, which can be quickly put into use.
In view of harsh environments such as coastal salt spray, northwest wind and sand, and low temperature on the plateau, Kechang switchgear has outstanding protection capabilities. The basic model has a protection level of IP4X and the high-end model has IP67. It can be soaked in 3 meters of water for 30 minutes without failure, effectively resisting salt spray, dust and other erosion. Its operating temperature range covers -40℃ to +55℃, and it can be started without preheating in a high humidity environment without dehumidification. It is perfectly adapted to special scenarios such as offshore wind power and high-altitude substations.


Hard-core and Reliable: Military-grade Quality Assurance
Reliability is the key to switchgear. Kechang adopts the dual technology of vacuum arc extinguishing and SF6 gas insulation, which can accurately cut off the fault current. The mechanical life of the product is as high as 30,000 times, which is about 3 times the industry average, and it has passed a number of rigorous type tests, including internal arc faults. Type test.The four-chamber independent separation structure and 20kJ-level pressure release channel provide multiple safety guarantees for equipment and personnel.
Relying on the IEC 61850 communication standard, this series of switchgear has achieved deep digitization. Built-in optical fiber temperature measurement and intelligent sensors monitor parameters such as contact temperature, local discharge and gas density in real time, and realize "telemetry, remote communication, and remote control" through remote signal output. The predictive maintenance model improves operation and maintenance efficiency by 70%, reduces comprehensive operation and maintenance costs by 45%, and moves towards "maintenance-free" operation.


Green and low-carbon: practitioners of a low-carbon economy
In response to the dual-carbon strategy, Kechang switchgear has continuously improved its materials and technology. Using continuous winding silicon steel sheet core technology, no-load loss is reduced by 40%; actively develop environmentally friendly gas alternative SF6 solutions to reduce greenhouse gas emissions. It has been estimated that a single equipment can reduce carbon emissions by about 20 tons in the whole life cycle, achieving a win-win situation between safe power supply and energy-saving economic benefits.
Market Feedback-Certifications
At present, Kechang classic switchgear series has passed a number of international and domestic certifications such as IEC, GB, CE, etc., and has been successfully used in a number of ±800kV UHV supporting projects and large-scale offshore photovoltaic projects. Its quality commitment of "one investment, 30 years of worry-free" is redefining the value standard of medium and high voltage power distribution equipment.
