Product Description
Product Overview:
GTXGN-12V solid insulated switchgear adopts modular structure design to realize any combination and expansion of switchgear cabinet for easy maintenance and maintenance. Fully insulated, fully sealed, maintenance free, all live parts are fully insulated. Fully insulated busbars are used for longitudinal arrangement, which is convenient and reliable. It has an independent low hvoltage room, which can be equipped with computer protection and various meters. It does not need to install a low-voltage chamber on the top of the cabinet to make the switch cabinets more beautiful and compact.

Switchgear Advantage:
• High-voltage distribution cabinets refer to electrical products that are used for switching, control or protection in power generation, transmission, distribution, power conversion and consumption of power systems, with voltage levels ranging from 3.6kV to 550kV.
• Generally, most power supply bureaus and substations use high-voltage switch cabinets, which are then led out through the low-voltage side of the transformer to low-voltage distribution cabinets, and then to the low-voltage distribution cabinets and then to various electrical.
• Equipment such as distribution boards, control boxes, and switch boxes to achieve the desired performance. Design functional requirements for electrical distribution equipment equipment.
Switchgear Features:
1. Use heat-shrinkable insulation materials and epoxy coating insulation technology to optimize the electrode shape, compact the cabinet structure, and reduce the floor space.
2. The switch cabinet body is made of high-quality cold-rolled steel and is formed by CNC sheet metal processing. It is connected by high-strength bolts, nuts and rivet nuts. The surface of the components is sprayed or galvanized.
3. The vacuum circuit breaker adopts SF1, SF2 type and F system sulfur hexafluoride circuit breaker to meet the needs of different users.
4. Each functional compartment of the switch cabinet is isolated by metal plates and equipped with independent pressure release channels.
5. Circuit breakers, grounding switches and other operations can be operated when the switch cabinet is closed, and the door can be closed;
6. The switch cabinet has strong structural adaptability, and the main wiring scheme can reach more than 198 types to meet the requirements of different application scenarios.
7. There is a mechanical interlocking device between the handcart, circuit breaker, grounding switch and rear cabinet door to prevent misoperation. The "five prevention" functions are complete, safe and reliable.
Switchgear Transport Packaging:
• Switchgear are packaged in three ways: wooden pallets, wooden frames, and wooden boxes.
• We generally use wooden box packaging, which can effectively protect the transformer during transportation
• Avoid collisions and keep the shape of the transformer intact
• Avoid corrosion, rust, etc. caused by environmental factors
