Power Transmission and Distribution System

• The core is made of high-quality cold-rolled grain-oriented silicon steel sheets, stacked with multi-stage 45° fully slanted joints;
• The product operates with low no-load loss and low load loss;
• The cylindrical structure provides good turn balance and strong resistance to short-circuit impacts;
• Vacuum oil injection and fully sealed structure improve internal insulation performance, reduce insulation oil aging, extend service life, and decrease partial discharge;
• The use of a corrugated oil tank or sheet radiator with elasticity accommodates the volume changes caused by the thermal expansion and contraction of the insulating oil;
• The surface of the oil tank undergoes derusting, degreasing, and phosphating treatment, followed by the application of primer and topcoat, meeting the special outdoor usage requirements for metallurgy, petrochemical systems, and humid and polluted areas;
• Maintenance-free, no need to replace the insulating oil;
