XGN15-12 box-type fixed AC metal-enclosed switchgear (I, II) uses sulfur hexafluoride switch as the main switch, and the whole cabinet uses air-insulated switchgear. It is suitable for power distribution automation, compact and expandable, with the characteristics of simple structure, flexible operation, reliable interlocking and easy installation. It can provide satisfactory technical solutions for various user requirements. Due to the adoption of sensor technology and the latest protective circuit breakers, coupled with advanced technical performance and light and flexible assembly solutions, it can meet the ever-changing requirements of the market. The main switches of XGN15-12 box-type fixed AC metal-enclosed switchgear (I, II) are original ABB SFG type SF6 load switches, FLN series load switches, permanent magnet mechanical vacuum circuit breakers, GE Power/VacVB type vacuum circuit breakers, etc. There are two operating modes: manual and electric.

XGN2-12 solid insulation ring main unit is a new generation of environmentally friendly composite insulation ring main unit developed by our company. It is a fully sealed power supply unit. All live parts and switches are fully sealed in an epoxy plastic shell. There is no SF6 gas in the shell. The entire switch device is not affected by the external environment, ensuring operational reliability and personal safety, and is maintenance-free.

TBBZ high voltage reactive power compensation cabinet is suitable for AC 5OHz, three-phase 10kV power series, used to improve power factor and adjust network voltage, thereby increasing the active output of power supply equipment and reducing line loss. This device is indoor (outdoor) type.

The SDTKR-12SF6 gas-insulated high-voltage AC metal-enclosed switchgear independently developed and produced by the company has passed the test of the National High and Low Voltage Electrical Equipment Quality Supervision and Inspection Center. The product is widely used in the 10kV/6kV transmission and distribution system of the State Grid, and is the preferred product for the power distribution system of various urban and rural users. The switchgear is a modular unit mode, which can be combined according to different uses; it consists of two categories: fixed unit combination and expandable unit, which meets the needs of various substations for flexible use of compact switchgear.

SDTKJL-12 high-voltage metering cabinet (box) (hereinafter referred to as "ground-type metering box") is suitable for the electric energy metering of high-voltage cable incoming users in AC three-phase AC 50Hz, rated voltage 10kV power systems. It can be installed on the roadside lawns of parks, residential areas, industrial and mining areas. The door can be opened directly to view the bottom of the meter and perform circuit breaker opening and closing operations on site. The ground-type metering box is mainly composed of vacuum circuit breakers, cast-type combined transformers, lightning arresters, live displays and intelligent control devices. Its metering methods include three-phase three-phase system and three-phase four-wire system. It can be equipped with zero-sequence current transformers for grounding protection. The floor-standing meter box complies with technical standards such as GB/T1984-2014 "High-voltage AC circuit breakers", DL/T402-2016 "High-voltage AC circuit breakers", DL/T 403~-2000 "Technical conditions for ordering 12kV~40.5kV high-voltage vacuum circuit breakers", GB/T17201-2007 "Combined transformers" and DL/T721-2013 "Distribution automation system remote terminals".

KYN61-40.5 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a three-phase AC 50Hz, rated voltage 40.5kV indoor complete power distribution device. It is used for receiving and distributing electric energy in power plants, substations and industrial and mining enterprises. It can control, protect and monitor the circuit and can also be used in places with frequent operations.This switchgear complies with GB3906-2006 "3.6kV~40.5kV AC metal-enclosed switchgear and control equipment", GB/T11022-2011 "High-voltage switchgear and control equipment standard" and IEC60298 "AC metal-enclosed switchgear and control equipment with rated voltage of 1kV and above and 52kV and below".

This switch cabinet is equipped with VS1 vacuum circuit breaker or VD4 vacuum circuit breaker with high breaking capacity and low cut-off value. It has the "five-protection" interlocking function of reliably preventing wrong operation, preventing load from pushing or pulling the trolley, preventing the circuit breaker from closing when the earthing switch is closed, preventing the earthing switch from closing by mistake when energized, and preventing the energized from entering the compartment by mistake. It is a power distribution device with superior performance.
