Product Introduction
◆ 35KV grade oil-immersed power transformer adopts new materials, new technology, new structure, optimized design and meticulous manufacturing
◆ The core material is made of high-quality silicon steel sheet with high magnetic permeability and low loss. The structure is a rigid frame structure with good stability, low noise and strong short-circuit resistance.
The winding adopts high quality oxygen free copper wire, good conductivity, low load loss. The winding is designed as an advanced longitudinal oil channel structure, with good heat dissipation effect, high electrical insulation strength and good impact resistance.
◆ The body is pressed by high-strength electrical laminate, all leads are firmly clamped, and the structure is scientific and reasonable.
◆ Plateau reinforced casing, suitable for high altitude areas.
The series transformer set up a full range of protection device, good technical performance, reliable operation.
