Porcelain Bushing Outdoor Termination

Product Introduction

Our company produces two main types of porcelain bushing outdoor termination, CN-YJZWC3 and CN-YJZWC4, 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, porcelain bushing, and wiping sleeve. 

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

Porcelain bushing is made of high strength inorganic electric porcelain with stable performance.

Porcelain bushing is using skirt structure, the overall is conical with good performance of pollution flashover resistant, climate resistant, anti-leakage marks, anti-erosion and water repellent ability.

The porcelain is filled with insulating oil with excellent electrical insulation properties, which also makes the mutual dissolution or penetration between silicon stress cone and insulating oil as low as 1/1000 to ensure the long-term safety operation of the product. Our product is using multiple sealing structures which can effectively prevent the immersion of water 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. 

Porcelain bushing has a long run safety operation history more than one hundred years in the power industry, which is the best example of a mature use. 

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 400~3000mm²;

Product Characteristics:

Reasonable Structure:high strength inorganic electric porcelain with stable performance, using skirt structure and the overall is conical with good performance of pollution flashover resistant, climate resistant, anti-leakage marks, anti-erosion and water repellent ability. Using multiple sealing structures which makes it improved and effective.
