Product Introduction

Our company produces two main types of composite bushing outdoor termination, CN-YJZWCF3 and CN-YJZWCF4, which are widely used for outdoor high-voltage overhead lines and cable connections with ANTI-pollution level of III, and IV.

They are composed of connector lug, stress cone, composite bushing, and wiping sleeve.

The stress cone adopts imported liquid silicone rubber injecting forming which has long-term stability of hold force and electric field uniform ability.

Composite bushing is made of a high-strength epoxy glass fiber sleeve which is covered over anti-climate insulating silicone rubber skirt outside the bushing, the overall is conical with good performance of pollution resistant, climate resistance, anti-leakage marks, anti-erosion and water repellent ability.

Filled with insulating oil with excellent electrical insulation properties, and the mutual dissolution or penetration is as low as 1/1000 between silicone stress cone to ensure the long-term safety operation of the product. Our product is using multiple sealing structures 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 fasteners are stainless steel with good waterproof seal performance.

The cross sectional areas range of cables with supporting accessories of various voltages is as following:

48/66kV~56/77kV 150~1400mm²;

64/110kV~76/138kV 240~1600mm²;

127/220kV~290/500kV 400~3000mm

Product Characteristics:

Composite bushing termination not only has all the advantages of the porcelain termination, but also has the following superior performance:

Mechanical property: The mechanical strength of the epoxy fiberglass of the inner layer is much better than that of porcelain bushing.

Anti-explode property: The silicone rubber skirts which covered the bushing is soft, and can effectively avoid or greatly reduce the damage after an explosion to personal or adjacent equipments, with better security than the porcelain bushing in densely populated areas.

Transportation property: the weight of composite bushing is less than 1/5 that of porcelain bushing. The excellent mechanical strength of inner layer and the soft texture of the outer layer make a better performance of compression resistance to collapse, effectively reducing the transportation and installation cost.

Anti-climate property: silicon rubber outside has excellent climate resistance property, pollution resistant and self-cleaning ability, UV and aging resistance. In IEC60815, it specifies that the porcelain bushing creepage ratio distance is only 17mm/kV, which is a little higher than the level I of pollution resistant. While the silicone rubber creepage ratio distance is up to 25mm/kV, reaching the level III of pollution resistant

Cleaning free property: silicone rubber has excellent water repellency with good self-cleaning ability, basically free blackout manual cleaning (porcelain blackout cleaning rate is generally once a year), greatly reducing the maintenance costs.
