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
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
Reasonable Structure：high strength inorganic electric porcelain
with stable performance, using skirt structure and the overall is

climate resistant, anti-leakage marks, anti-erosion and water
repellent ability. Using multiple sealing structures which makes it
improved and effective.
