Product Description

Corner bone/dogbone (glass fiber composited with polyester resin ) with certificate of UL/ROHS/REACH


Corner bone and dogbone are the pultrusion material which were produced by mold .The raw materials are polyester resin and glass fiber roving . Fiberglass roving were impregnated in polyester resin ( added some filler materials in polyester resin) , and then pultrusion under high temperature and pressure .It is the glass reinforced thermoset polyester material and will became the solid material while temperature rise up .

We have so many sizes of options by clients , such as 8*8/10*10/12*12/16*16mm (total more than 20 kinds of the size ) and the length can be customized by clients , it will be very convenience for making parts of clients .

Corner bone with very excellent properties on Electric/ mechanical properties, it is very strong, dimensionally stable and impact resistant of mechanical properties .No cracking when assemble in electric equipment. At the same time ,it has so many advantages on properties , such as good properties on flame, arc and track resistance etc.

The material has certified by ROHS/REACH for meeting environmental requirements .

To meet the requirement for exporting to Europe and North America , the produce has certificated by UL.

At present ,this materials have been exporting to so many transformers manufacturers in Asia and Europe and total more than 20 countries .

Feature of dogbone and corner bone


It is the environmental protection material , very little effect to the environmental when running in electrical equipment.

It is halogen free product and green products , meet ROHS and Reach requirement and no effect to the human bodies .

It can be customized produce as per client’s requirement .

Very stable of the strength such as tensile & bending when running on high or low temperatures , no cracking .

It is the fire resistance material and low smoke material .

Very excellent properties on arc (more than 180s) and CTI meet CTI600;


Application of material 

Dogbone and corner bone with very good properties when working temperature below zero degree centigrade,we have the clients who was running projects in Qinghai-Tibet Railway , the temperature will below -55℃ in winter .However , the material will keep the excellent electric and mechanical properties in this extreme temperatures .

These properties were tested by the third party which is one of the most famous Accredited Testing Organization in China.

This material can be machined parts such as drill the holes by CNC machines . In addition ,the material with the excellent electric properties , especially excellent anti Comparative Tracking .As we known , voltaic arc caused carbonization on surface of material , and the carbonization will affect to the insulating property , this material will reach more than 180 seconds of arc voltaic.

Corner bone produced by polyester resin and glass fiber is widely used in area of transformers . reactor , large dry type transformers and etc., researching and development of the application characteristics of airway stay pultrusion products . With the advantage in the process of foil or wire wound around the stability of bracing structure and non-cracking .


with the Environmental protection concept enjoy popular support , more and more electric equipment manufacturers will be choosing green products to produce the electric product , ROHS/REACH certified material meet this requirement .
