Description:

1, 66kV(63kV)composite polymer insulator are widely used in 66kV(63kV) overhead transmission lines and substations.

2, Dead end fittings are up to the requirements from the clients, usually we use ball, socket, tongue, clevis for suspension insulators with forged steel or cast steel. The dimensions and coupling size can be exactly according to the specification requirements from the utilities.

3, The silicon rubber color of the insulators are also up to the requirements from the clients and all the silicon rubber materials past 5000 hours aging test silicon content test and hydrophobicity test.

4, ECR core rods are used in all the insulators, so we can guarantee a very good mechanical strength and anti-acid pollution performance for the insulators.

5, All our insulators were type tested and design tested in accordance with IEC61109, maximum RIV is 100µV when tested at 1MHz and10% over nominal line ground voltage for indicated system voltage.

Applications:

1, 66kV(63kV) overhead transmission power lines.

2, 66kV(63kV)substations

Competitive Advantage:

<

The advantages of polymer/composite insulators over ceramic/porcelain insulators
General comparison
Factor	Ceramic/porcelain insulators	Polymer/composite insulators
Weight	Heavy weight- For example 400kV - about 140kgs	90% lighter than them but with same mechanical strength 400kV -- Around 15kgs
Fragility	Highly fragility to shock and vibration	No fragility to shock and vibration
Packing and transportation	Risky and very costly	Easy and economical
Installation	Risky expensive and more labor required	Very easy and economical
Handling	Difficult	Easy
Maintenance cost	Very expensive	Low
Vandalism	More susceptible	Highly resistant
Breakages and secondary damage	Highly fragile- 10-15% breakages are reported during transportation storage and installation	Flexible and therefore highly resistant to breakages
