Environmentally friendly gas-insulated ring main unit

The GT-HRM-12 environmentally friendly gas-insulated ring main unit is a standardized, custom-designed 12 kV product independently developed by Jubang Group Co., Ltd. in response to the national drive for standardizing distribution networks and in compliance with the principles of safety, reliability, robustness, durability, and universal interchangeability, thereby enhancing the operational reliability of ring main units. The product incorporates state-of-the-art production equipment and manufacturing technologies, offers flexible configuration options—either modular or common‑box designs—and replaces SF6 with a safe, environmentally friendly mixed gas as the insulating medium within the gas compartment, effectively addressing the issue of SF6 leakage and associated environmental contamination.

KYN28A-12 Armored Withdrawable AC Metal-Enclosed Switchgear

KYN28A-12 is suitable for three-phase AC power systems operating at 50 Hz. It is primarily used in power plants, for power transmission from small and medium-sized generators, for distribution in industrial, mining, and institutional facilities, as well as for receiving and transmitting power in secondary substations of the electric utility system, and for starting large high-voltage motors, thereby providing control, protection, and monitoring functions. This switchgear complies with the requirements of standards such as GB/T 11022 and GB/T 3906. It features interlocking functions that prevent operations such as pushing or pulling the circuit breaker handcart under load, inadvertent opening or closing of the circuit breaker, closing the circuit breaker while the earthing switch is in the closed position, entering a live compartment by mistake, and mistakenly closing the earthing switch when energized. It can also be equipped with our company's…
