The KYN28-12(Z) 7.2KV 1600A High Current Power Distribution Cabinet Switchgear is designed for 12kV rated voltage and 50Hz rated frequency in three-phase AC power systems. This equipment is utilized to manage the reception, distribution, control, protection, and monitoring of electrical circuits.

In recent years, engineering construction has become increasingly intricate due to the growth of society, the economy, and technology. There is a rising trend towards smaller, smarter switch equipment that demands minimal maintenance. Manufacturers, both local and global, are focusing on the development of the 40.5kv 2000A High Voltage Sf6 Gas Insulated Switchgear, also referred to as gas-insulated switchgear (C-GIS). These switchgears house high-voltage elements like busbars, circuit breakers, isolating switches, and power cables within a protective shell with reduced gas pressure.

The KYN28-12(Z) AC metal armored switchgear 3.6KV 3150A Medium Voltage High Current Electrical Switchgear is designed for three-phase AC power systems with a rated voltage of 12kV and a rated frequency of 50Hz. It serves as a reliable and efficient solution for receiving, distributing, controlling, protecting, and monitoring electrical energy in various applications.

145KV 3150A Earthing switch,The neutral point serves various functions, contributing to distinct technical characteristics and operational requirements. The BJ-type transformer neutral point gap grounding protection device plays a crucial role in preserving operational reliability, equipment insulation, and protective measures to ensure consistent performance.

Product Overview This circuit breaker is a low-voltage protection device designed for AC 50/60Hz power distribution networks with rated voltages up to 400V and currents up to 63A, suitable for industrial, commercial, and residential electrical systems. It integrates comprehensive safety and operational safeguards: High-sensitivity Residual Current Detection (RCD) technology provides indirect contact protection to mitigate electric shock risks, while overload long-time delay protection and short-circuit instantaneous tripping ensure precise fault current interruption, preventing equipment damage and fire hazards. The device also supports infrequent circuit switching and intermittent motor start-stop operations, meeting flexible control demands in standard power distribution scenarios. Key Features & Applications Featuring a modular compact design compatible with global power standards, it is ideal for data centers, manufacturing facilities, and building distribution panels, particularly in environments requiring high power continuity and safety. The thermomagnetic dual-protection mechanism guarantees stable overload response and rapid short-circuit breaking, enhanced by 50/60Hz frequency compatibility for robust system reliability. With a durable construction and rail-mounted quick installation, it serves as a reliable solution for modern smart grids, balancing safety, efficiency, and ease of maintenance.
