The advantages of polymer insulators:

1: The polymer insulator has the advantages of high strength, light weight. Can relieve stress, reduce the installation and maintenance of towerof strength, save costs. Because the rod core with tensile strength is high so the composite insulator can be very handy.

2: composite insulator aging resistance, good. Composite insulator has good corrosion resistance, aging resistance, at 70 degrees Celsius is elastic, can be long - term work 20 degrees celsius.

3: composite insulator has the advantages of small volume, light weight. Because the composite insulator has the advantages of small volume, light weight, and the umbrella disk is flexible, not easy to damage, so it brings great convenience to the transportation, installation, maintenance.

Company Profile

Dalian Composite Insulator Co., Ltd. with strong researching and developing capability, mainly produces 10-500kv series composite insulators. We are a high-tech enterprise which integrates insulator design, production and sales into a whole body. Our products are all according to relative international standard and we have gotton certification of ISO9001.

Our main products are high voltage composite insulators, including long rod suspension composite insulator, pin type composite insulators, composite crossarm insulators, composite post insulators, composite bushings, and composite insulators for electric railways. Assembly products include composite arrester, cut-out and disconnecting switch.

For shed and housing moulding, we adopt international advanced method of whole moulding and whole injection. The connection zone between the core and end fitting compressed with crimping machine. The products have the haracteristic of artistic looking, small volume, light weight, uneasy broken, high bending and torsion strength, good anti-explosive performance, easy transportation and installation.

We adopt un-puncture design to ensure its safe operation. Reliable structure to make the core safe and reinforce the mechanical strength. Our product are especially suitable to high polluted areas, high mechanical tensile load, long span and compact lines.

Our advanced management system, excellent engineer team, international standard equipment and complete test technique lay us a solid foundation for development and production of new items.

If you are interested in cooperating with us, please contact us for more information. We hope we can establish a sound business relationship with you, and we will strive to meet all your business and product needs.
