66kV-500kV Composite Bushing Outdoor Termination:
Our company produce two main series of composite bushing outdoor termination, 4E-YJZWCF3 and 4E-YJZWCF4, which are widely used for outdoor high-voltage overhead lines and cable connections with antifouling grade of grade III, and grade IV. They are composed of termination, stress cone, composite casting bushing, and tail tube. We use imported liquid silicone rubber injection molding to make stress cone, which has long-term stability of lasting hold power and electric field uniform ability. Composite casting bushing is using skirt structure with high strength epoxy fiberglass insulation tubes coated with silicone rubber. The composite casting bushing is filled with insulating oil with excellent electrical insulation properties, and the mutual dissolution or pentration is as low as 1/1000 between silastic stress cone to ensure the long-term safe operation of the product. Our product is using multiple sealing structure which can effectively prevent the leakage of water immersion and insulating oil. All of the seals are using imported NBR or silicon rubber material. All of the fastener raw-material are stainless steel with good waterproof seal performance.
Composite bushing outdoor termination not only has all the advantages of the porcelain bushing, but also have the following superior performance:
Mechanical: mechanical strength of the inner layer is epoxy fiberglass which is better than porcelain bushing, with better mechanical performance.
Explode proof: silastic skirt layer covering outer is soft, effectively avoid or greatly reduce the damage after an explosion caused by personal or adjacent equipment, with better security than the porcelain bushing in densely populated areas.
Transportation: the weight of composite casting bushing is less than 1/5 of porcelain bushing weight. The excellent mechanical strength inner and soft outer layer is more compression resistance to collapse, effectively reducing the transportation and installation cost.
Weather resistance: silicon rubber outer layer has excellent weather resistance, stain-resistance self-cleaning ability, UV and aging resistance. IEC60815 clearly shows that the porcelain bushing creepage distance is only 17mm/kv, slightly higher than the level of anti-I, while the silastic creepage distance is up to 25mm/kv, reach the level of anti-III.
Cleaning free: silicone rubber has excellent water repellency with good self-cleaning ability, basic free blackout manual cleaning ( porcelain blackout cleaning rate is generally once a year), greatly reduce the maintenance costs.
