Description
Product Introduction
This 10/0.4/0.1kV three-winding metering service dry-type transformer is specially designed for supporting use in medium voltage switchgear, high voltage switchgear, and ring main units. Adopting a special structure, it optimizes the outline dimensions while meeting all standard performance parameter requirements and installation specifications of medium voltage switchgear and high voltage switchgear. It is currently an ideal supporting transformer for medium voltage switchgear and high voltage switchgear.
The primary side directly draws power from the busbar. The secondary side is generally equipped with one winding (0.4kV) for on-site power supply and lighting. According to customer requirements, an additional winding (0.1kV,50VA) can be added for measurement, control, and protection of on-site equipment.
Performance Features
- Safety & Environmental Protection: Safe, fire-proof, and pollution-free. It can be directly installed near the load center.
- Superior Technology: Equipped with German HTT technology. Features high mechanical strength, strong short-circuit resistance, low partial discharge, excellent thermal stability, and low loss.
- Compact Design: Small volume, light weight, space-saving, and easy for installation.
- Energy-saving & Maintenance-free: Low noise, maintenance-free, and remarkable energy-saving effect.
- Environmental Adaptability: Moisture-proof, mildew-proof, and salt spray-resistant. Exhibits excellent heat dissipation and is suitable for high altitude, high temperature, and other harsh environments.
- High Insulation Performance: Excellent insulation performance and high electrical strength.
