• It is organic insulation typeproduct. The external insulation is silicone rubber petticoat.
• Electric field evenly distributed, partial discharge small amount and stable, small dielectric loss.
• The current ratio can be changed easily by changing the connection method in shielding enclosure to facilitate the realization to series or parallel connection.
• All parts, such as stainless bolts, name plate are rust-free all the time.
• The product has no oil, no ceramic, no gas.
• Barely need for maintenance. Measurements of the capacitance and dielectric loss factor at primary side are needed every 2~3 years.
• If you have special requirement for our product, please add note explanation
