Low-voltage switchgear (MDmax ST cabinets, GCS, GGD)

MDmax‑ST is a high-end modular switchgear cabinet that supports mixed configurations of withdrawable and fixed units, features comprehensive arc‑quenching protection, and can be expanded with intelligent power‑distribution monitoring; it is ideally suited for critical projects requiring high reliability. GCS is a withdrawable MCC cabinet with highly interchangeable modular drawer units and a high degree of multi‑circuit integration, meeting the needs of motor and power distribution while allowing maintenance without interrupting busbar power. GGD is a fixed‑type distribution cabinet characterized by a simple, well‑proven structure, excellent dynamic and thermal stability, and outstanding cost‑effectiveness; it is commonly used for incoming feeders, bus tie circuits, and reactive‑power compensation, making it well suited to distribution applications with low operational frequency. All three series comply with the GB/T 7251 standard family and can be selected and configured according to project reliability requirements and operation‑and‑maintenance considerations.

Metal-enclosed armored switchgear (KYN61-40.5, KYN28-12)

KYN28-12 and KYN61-40.5 are indoor, armored, withdrawable, metal-clad switchgear units, designed for 12 kV and 40.5 kV three-phase AC power systems operating at 50 Hz. They provide power reception and distribution, as well as circuit control, protection, and monitoring functions. The cabinet is divided into independent compartments and equipped with withdrawable vacuum circuit breakers, featuring a comprehensive five‑preventive interlocking system. These units can be fitted with intelligent components for protection, temperature measurement, partial discharge detection, and more, enabling integration into smart distribution systems. They are widely used in substations, industrial enterprises, new‑energy facilities, and other power distribution applications.

AIR CIRCUIT BREAKERS(ACBS)AUTOMATIC

TW30series intelligent aircircuit breaker is applicable to power distribution networks of AC 50Hz, 400V, 690V with rated current ranging from 630A to 6300A. It is used for electric power distribution and circuit protection, protecting powersupply equipment against hazards caused by overload, undervoltage, shortcircuit, singlephase earthing and other faults.
Equipped with multiple intelligent protection functions, the breaker realizes selective protection with precise tripping action, avoiding unnecessary poweroff and improving powersupply reliability.
