ANSI 57 series composite line post insulators

ANSI 57 series composite line post insulators used on distribution line and transmission line is up to 132KV. The raw material used for designing these composite line post insulator products is best quality.

ANSI 57 series composite line post insulators are more susceptible to degradation by electrical discharges a number-one enemy for the composite materials. To a large extent this can be controlled by well designed and dimensioned corona rings, however one can not do much under wet conditions. Our offered ANSI 57 series composite line post insulators are designed with the keen observation by using finest raw material along with the updated technology.

ANSI 57 series composite line post insulators is manufactured by protrusion process using boron free ECR grade glass fibre having requirement mechanical and electrical characteristics. These terminals can be manufactured in different shapes and materials, according to the IEC 60120, IEC 60471, and IEC 61466-1 standard and according to the characteristics requested by the customer or their use.

Major development efforts have been carried out to achieve our optimized composite insulator shed profiles. The routine test is to inspect each piece of ANSI 57 series composite line post insulators. Each of ANSI 57 series composite line post insulators is ISO 9001 certified and is governed by the same quality assurance programs and organization.
