Product characteristics
Specification three The aluminum clamp of the porcelain casing is made of high-strength aluminum castings to reduce eddy current losses.
The insulating pillars of the product are all made of porcelain insulating parts, with reliable insulation performance and larger creepage double distance, and are suitable for general dirty areas.
The product contacts and contact finger blades adopt line contact, and the contact resistance is small. In particular, the large current structure design is relatively reasonable, the loop resistance is small, and the structure is compact.
