• The product adopts case-type structure, Its central part adopts Silicone RubberComposite Insulating Bushing orHigh StrengthPorcelainBushing and top part is settled with primary Terminals
• Case bodyis equippedwith SF6 Density Controller which has a function of temperature compensation and agroup of junctions for providing alarm signal.
Case body lateral parts are installed pressure relief devices with a pressure relief of 1.0Mpa and advantages of no oil, norisk of explosion and no maintenance
• The equipment body is placed in the case. The layer insulation is high strength composite insulation of-polyester Film and gas SF6-Gas SF6 has a reliable insulation performance, no worry of aging and function of insulation restoration.
• Case body has been Plastic spray treated. All Parts, such as stainless bolts, name plate are rust-free all the time.
• The primary connection adopted Aluminum Alloy can support>3000N static testing load
• Seal Rings adopted material of 1 Fluorinated Rubber is suitable for areas ofgreat temperature changes and harsh environment t emperature, with annual leakage rate<0.5%.
• It makes the product capacitive under a certain voltage to adopt higher saturation flux density Magnetic Material, advanced technology and excellent insulation design.
• If you have special requirement for our product, please add note explanation
