Wenzhou haibo  cable accessories co.ltd. is a company invested and controlled by Zhejiang Haivo Electrical Co.Ltd.Specializing in the developing, manufacturing and marketing of middle and high voltage power cable accessories and IEC/IEEE type Separable Connectors.Its profucts cover 35kV and below 35 kV distribution networks as well as 220kv high voltage transmission lines.
We have international advanced rubber injection molding equipments, it guaranteed the superior performance of the product. At the same time, All kinds of testing equipments is fully equipped, we have high voltage test lavs with AC voltage withstand up to 900kV, and partial discharge test lab. We grarantee 100% product qualification.
We were successively awarded ISO 9001:2015 by DAS CERTIFICATION LTD & UKAS QUALITY MANAGEMENT, and TYPE TEST CERTIFICATES by CHINA NATIONAL HIGH VOLTAGE LABS.
We promise we will offer first-class quality, reasonable price, first- class service and following the business philosphy of development and innovation to serve global power customers!

Feature of product:
Technique of full cold shrink:
Without fire work and special tools, simply pull the wick gently, will retract rely on its own elasticity, so attaches to the cable closely, each specification can be applied to a variety of cable diameter, strong compatibility with cable diameter.
Reliability of insulation:
Using liquid silicone rubber to ensure good insulation and high elasticity. Always maintain constant radial pressure on cable body after installation, insulation main body of product and electrical stress control unit preform as a whole in factory, little partial discharge capacity, "breathing" with cable body simultaneously.
Stable performance:
Supporting tube using ultrasonic welding, to ensure the reliability and stability of the products, permanent tensile and lower deformation rate, improve the warranty period of products.
Reliable sealing:
The terminal body coordinate with cold shrink branch finger sleeve, cold shrink insulation pipe and cold shrink terminal seal tube; The intermediate joint kits adopt with three layer of waterproof sealing technology, to ensure excellent seal moisture performance of accessories.
Easy for installation:
Simple installation, convenient operation, easy to master. Stripping distance is short and installation space demand is little while pretreatment of cable. Grounding method by using constant force spring to fix the earth lead
without welding or tied copper wire, and one end of the ground has been compressed with terminal, more convenient installation, safe and reliable.
Widely Use:
Pollution resistance, ageing resistance, good hydrophobic, and have excellent corrosion resistance, cold resistance and resistance to ultraviolet ray, to ensure the long-term and stable performance usage. Especially suitable for high altitude, cold, damp, salt fog and heavy pollution areas.

Reliable stress control method for cold shrink cable accessories
Haivol 18/20kv High Voltage 3-Core Cold Shrinkable Joint Kit Applicable of Cable Cross-Section 95mm^2
At present, there are two kinds of stress control modes such as stress cone and stress pipe in the power cable accessories of 35 kV and below voltage. Using the method of stress cone alleviate stress concentration of electric field, it's the most reliable and most effective method from the electrical point of view.
Stress cone by cutting the insulation shield for outspread, make its form a trumpet-shaped, improved the distribution of electric field, reduce the electric field intensity of fracture surface of outside semi-conducting layer, maintain the operating life of the cable. It is also to use stress cone control method to homogenizing the electric field in the system of 110 kV or higher voltage.
If choose the stress control tube method, the material dispersion is large of the stress control tube, disadvantages such as the product performance is not stable and the holding force is small between the accessories and cable insulation, etc. So we choose the high reliability of stress cone control mode.
