Overview
Huabian was developed by Chinese consumers by leveraging Meibian's excellent heat dissipation performance and Oubian's comprehensive protection features, optimizing its compact structural design to solve the problems of Meibian's lack of protection and poor heat dissipation, with current market promotion prospects.
Product features
• Huabian is divided into three parts: high-voltage chamber, low-voltage chamber, and transformer, arranged in an "L" or "pin" shape;
• Huabianli transformers can only use oil-immersed transformers; dry-type transformers are not allowed;
• The transformer body and heat sinks of Huabian transformers are exposed outside the enclosure, providing good heat dissipation. The remaining live compartments are sealed in independent compartments, each compartment separated by partitions, and a lower manhole is provided inside the enclosure for easy installation and maintenance;
• The casing is made of cold-rolled steel or stainless steel plates, with smooth inner and outer surfaces, no rust, coating peeling, or damage from bumps. The coating layer is firm and uniform, with no obvious contrast or reflection;
• The cabinet top cover is equipped with a rainproof sealed cover plate and rainproof eaves; the double-layer structure of the cabinet top cover prevents heat radiation;
