Introduction to PINEELE GTXGN-12 금속 클래드 스위치 기어
그리고 PINEELE GTXGN-12 Metal-Clad Switchgear is a medium voltage switchgear system designed for indoor three-phase AC 50/60Hz power networks with a rated voltage of up to 12kV. Engineered to meet the growing needs of modern electrical infrastructure, this metal-clad switchgear offers a compact, modular, and safe solution for energy distribution in power stations, industrial zones, commercial buildings, and renewable energy applications.
Conforming to international standards such as IEC 62271-200 그리고 GB3906, the GTXGN-12 Metal-Clad Switchgear utilizes vacuum circuit breakers, gas-tight compartments, and fully metal-enclosed bus systems. This makes it an ideal choice where space-saving, personnel safety, and reliable service continuity are crucial.
Key Features of PINEELE GTXGN-12 Metal-Clad Switchgear
Fully Metal-Enclosed Structure
- Each functional unit (breaker, busbar, cable, control) is sealed and independently isolated.
- High-level arc-proof construction and IP4X/IP2X protection for personnel safety.
Flexible and Modular Configuration
- Designed for both single bus 그리고 double bus systems with optional bypass schemes.
- Handcart-based withdrawable modules for easy maintenance and inspection.
High Dielectric and Mechanical Strength
- Advanced vacuum breaking technology ensures long service life and reduced arc erosion.
- Tested for short-circuit withstand, dielectric strength, and partial discharge immunity.
Enhanced Safety with Interlocks
- Integrated mechanical and electrical interlocks to prevent access during live operation.
- Prevents circuit breaker racking, grounding switch misuse, and door opening under load.
