69kv 70KN Silicone Rubber Composite Insulator for Support Cable

Insulators are widely used in overhead transmission lines to provide mechanical support and electrical protection, as well as in distribution lines and substations. Silicone rubber is the most widely used polymeric insulation material for high voltage insulators.HAIVO brand composite insulator made of silicone rubber.Depending on voltage considerations, different kinds of insulators are used in power systems,we have Pin insulator,strain insulator,suspension insulator.post insulator,long rod insulator,horizontal post insulator,Railway insulator,shackle insulator,stay insulator.

Availability:

Long rod suspension insulator:

lightweight, unbreakable, hydrophobic, resistant ozone UV radiations, resistant earthquake

Long rod suspension insulator ?Composite insulators for high voltage overhead power transmission line application

For rated voltage up to 550 kV power transmission lines supporting, suspending and insulation.


Ratings: Up to 500kV.


Standards: IEC 61109


Composite Insulator for AC Power Distribution System


Features: Secure and reliable operation on high mechanical strength. Compact design and light in weight which is convenient for transportation. Good anti-vibration capability. Good anti-moisture capability. Good electric performances Strong anti-pollution falshover ability. High anti-aging performances which is perfect for utilization under conditions of high altitude. Easy for maintenance.


Product range:

Long rod Composite insulators up to 500kV.

Pin Composite insulator up to 36kV.

Post Composite insulator up to 252kV.

Line post Composite insulator up to 36kV.


Technology characteristics:

1)The silicone rubber housing taken shape by whole injection has good hydrophobicity, drophobicity migration and soil resistance, as well as excellent electrical insulation roperties and aging resistance, which could prevent effectively those accidents of pollution flashovers so as to ensure the safe running of high voltage transmission lines.

2)The modified ECR fiberglass reinforced epoxy resin rod is used as it has good resistance to high temperature, stress corrosion &acid attack, as well as fine damping action, high tensile strength( >1200Mpa ) and resistance to creep and fatigue failure, which effectively ensure the internal insulation quality and mechanical strength of insulators.

3)End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper , The insulators with this crimping technique have high mechanical strength and small dispersion.

4)The connection location between end fittings & rods is fused with sheds housing by the overall high tempera- ture vulcanized silicone rubber injection molding as it could minimize the interface. 

5)The internal radial multi-seal structure effectively guarantees a long-term reliability of seal around the connection between end fittings & rods.


Note:

1 Applicable stardand:IEC,ANSI,GB and other international standard

2 Normal colour of the composite insulator:red,gray and white.

3 Special design according customer's requirement.
