High Voltage Panels
Product Overview
High voltage panels are specially designed for power systems above 3kV and include Air Insulated Switchgear (AIS), Gas Insulated Switchgear (GIS), and Ring Main Units (RMU). According to voltage classifications, the equipment is divided into medium-voltage, high-voltage, and ultra-high-voltage categories.
The high voltage panels are manufactured in strict compliance with the GB/T 11022 general technical standard. A mandatory five-prevention interlocking system is integrated to eliminate operational errors from both mechanical and electrical aspects. The cabinet structure adopts thickened sheet metal with anti-corrosion treatment, offering excellent dustproof performance, corrosion resistance, and insulation capability for harsh industrial and outdoor environments.
Core Product Features
- Standard five-prevention interlocking system ensures a high level of operational safety and reduces human error risks;
- Multiple insulation options are available, including air insulation and gas insulation, to meet different space and project budget requirements;
- Rational internal partition structure with independent busbar, circuit breaker, and cable compartments for stronger fault isolation capability;
- Designed to meet strict power grid operating standards with stable performance and convenient maintenance.
Our high voltage panels are engineered for reliable power transmission and distribution performance under demanding electrical operating conditions.
Application Fields
- Substations;
- Thermal power plants, wind farms, and photovoltaic power stations;
- Metallurgical, chemical, and mining enterprises;
- Rail transit power distribution systems;
- Urban and rural backbone power grids.
The equipment is widely used in high-voltage transmission and distribution applications requiring secure and stable electrical operation.
Enterprise Quality Control & After-Sales Advantages
The company implements a complete five-level quality control system covering raw materials, supply chain management, production, inspection, and delivery. Every product undergoes 100% inspection before packaging. Third-party inspections are also accepted without affecting the agreed payment schedule.
A dedicated after-sales service team is provided, and all power distribution products include a 2-year warranty. Pre-sales services include technical consultation, drawing optimization, and bidding document support. During production, the company provides full progress management, while after-sales support covers project acceptance, inspection and maintenance services, and technical guidance.
