Product Description
Our ac metal enclosed switchgear is designed for primary medium-voltage distribution where operating safety, circuit separation, mechanical interlocking, and maintenance access are essential. The KYN40.5(Z)/T1600-31.5 configuration is a 40.5 kV class metal-enclosed system with a rated current of 1600 A and a short-circuit breaking rating of 31.5 kA, as indicated by the model designation. It can be arranged for incoming lines, outgoing feeders, bus sectionalizing, transformer protection, metering, and station service according to the project single-line diagram. The ac metal enclosed switchgear uses a compartmentalized cabinet structure to organize the circuit breaker, busbar, cable, and low-voltage control areas. This separation supports safer inspection and helps prevent one functional area from becoming an uncontrolled access path to another. Interlocks can be engineered to coordinate breaker position, isolation, earthing, and door access so that normal operating sequences are clear to trained personnel. The cabinet layout also considers lifting, transport, on-site joining, cable termination, and maintenance space, which are critical in high-voltage rooms where installation errors are costly to correct.
Jiangsu Guoxing Electric Equipment Co., Ltd. manufactures ac metal enclosed switchgear with factory-direct control over the enclosure, internal assembly, wiring, inspection, and documentation. The company has operated since 1984 and maintains a 36,000-square-meter facility with more than 200 sets of production and test equipment. CNC sheet-metal processing supports dimensional accuracy, while the test center includes equipment for electrical performance, surge, transient, electrostatic-discharge, high- and low-temperature, salt-spray, and dust-rain verification for applicable product lines. The ac metal enclosed switchgear can be customized with specified vacuum circuit breakers, protection relays, current and voltage transformers, meters, communication devices, arc-detection options, and cable interfaces. We can manufacture from technical drawings or develop the arrangement from a customer specification. Before packing, every cabinet undergoes 100% inspection and an inspection record can be supplied. Third-party inspection is accepted when the buyer provides the relevant standard and technical requirements. For agents and engineering companies, this creates a clear chain of responsibility from design review through production, testing, packing, and after-sales support.
