Product Introduction

10-36kv HDPE pin type insulators are used on distribution lines, low weight, easy to transport and installation, 100% recyclable.

  Polymeric HDPE insulators is made of High Density Polyethylene, this type insulator is applied to medium and high voltage power line to support conductor and insulate from ground. 10kv-36kv is usually used because of its advantage of light weight and easy to handle and transport and install. 100% recycle makes it environment protected.

  Except HDPE material, Orient Insulators also add some additives, such as anti-UV, anti-aging, and etc, to make the insulators more suitable for the environment and have long life span. The final color of the insulator can be adjust according to client requirement, but normally it is grey.

  The HDPE insulators (High Density Polyethylene) need assembly with spindles, and better with plastic head type spindle, we developed the spindle together with the HDPE insulators and bond together to get better strength and insulation. The top and side grooves can be designed to accept conductor sizes in the range of customers’ requirement.

  The thick wall and especially thick head of the HDPE insulators make it is hard to inject by traditional ways, and it need more time to cure, and cooling. Orient can produce the insulators without voids in it, and every of our insulators will be detected by the laser.

Product Parameters

You can provide the following important parameters of to us, we can choose our current HDPE insulators for you according to the parameters or open new molds to provide exact insulators.

Essential parameters for polymeric HDPE insulators:

 

>system or rated voltage

>creepage distance

>neck diameter dimension

>specified cantilever load

>with spindle or not

 

Except the above, other special requirements by the end user are needed.

Packing: cartons with pallet, suitable for seafreight or airfreight.

Production cycle: 30-45 days
