Why Choose Evernew’s Explosion Proof Mining Transformers?
Industry-Leading Safety Features
Our Explosion Proof Dry Type Transformers are constructed to withstand harsh conditions, specifically in mining operations where explosive gases and coal dust are prevalent. The housing is engineered with sealed, moisture-proof, corrosion-resistant, and explosion-proof features. We use high-quality NOMEX® insulation materials for maximum fire resistance and long-term reliability. Whether operating in extreme heat or challenging weather, our transformers maintain high performance standards, minimizing operational risks.Innovative, High-Quality Construction
Our transformers are designed with cutting-edge materials and construction methods:- High-Strength Shell: The outer casing is crafted using German corrugated metal, ensuring high mechanical strength and excellent cooling performance. The transformer’s compact structure enables easy installation and transportation.
- Advanced Core Design: The core is made of high-permeability cold-rolled silicon steel, offering low losses and noise, maximizing efficiency and lifespan.
- Specialized Insulation: The core and windings use H-class insulation, with Dupont Nomex® papers, providing exceptional dielectric properties. This advanced insulation system helps maintain peak performance even under high temperature conditions (up to 180°C for Class H).
Reliability and Performance in Hazardous Areas
Our Explosion Proof Transformers meet stringent industry standards for operating in dangerous environments:- Safe Operation in Hazardous Locations: The transformer can safely operate in underground mines, chemical plants, and quarries, even in areas with flammable methane gas or coal dust. The transformers comply with ExdI and ExdII explosion protection standards.
- Long-Term Durability: Designed for environments with high vibrations, our transformers are built with robust structures to endure extreme conditions without failure. The internal components are carefully assembled to ensure they can withstand overloads, short circuits, and temperature variations.
Compact, Easy to Transport and Install
- Space-Saving Design: These transformers are compact and lightweight, making them ideal for tight spaces and easy installation.
- Versatile Transport Options: Equipped with a sliding chassis, the transformer can be easily moved to different areas within the mine. For added convenience, a roller-equipped base allows for mobility, providing flexibility in installation.
- User-Friendly Setup: Eight-point fixing enables quick and secure vertical entry, while the unique terminal box design ensures hassle-free connection.
Advanced Monitoring and Control
Each transformer is equipped with a built-in monitoring system that provides real-time data on operational status. This system helps operators avoid faults and enhances operational safety. Parameters can be transmitted to the control center via RS485/232 interfaces, allowing for seamless control and monitoring.
