Product Detail

Description

Performance characteristics

01. The core is processed by domestic high-quality oriented silicon steel, and the end surface of the yoke is coated with special resin glue, with low loss, low noise and stable performance

02. The low-voltage coil layer is made of pre-immersed DMD winding, cured at high temperature, with good insulation performance and high overall strength.

03. high pressure coil adopts segmented multi-layer cylinder structure, longitudinal airway, vacuum pressure pouring, high mechanical strength, strong short circuit resistance, low, moisture-proof, dust-proof, salt spray prevention ability

04. The overall structure design is simple, reasonable, beautiful and generous, easy to use and maintain.
