Composite insulator (Polymeric insulator)

What is composite insulator? Composite insulator is also called polymeric insulator. It is developed after toughen glass insulator and ceramic insulators, whose main insulation structure is consist of a fiber glass core (rod) and silicon housing and sheds. One both side, 2 metallic fittings are installed on each side with crimping technics. These 2 metal […]

Porcelain Post Insulators

Porcelain post insulators are widely used on electrical power substation and transmission line systems. In substation line system,post insulators are commonly seen as station post insulator.On both sides of station post insulator there are flanges with drilled holes for bolts fixing. These station post insulators are fixed on bottom base and with bus bar support […]

Porcelain stay insulators

For low voltage lines, the stays are to be insulated from ground at a height. The insulator used in the stay wire is called as the stay insulator and is usually of porcelain and is so designed that in case of breakage of the insulator the guy-wire will not fall to the ground.

Porcelain pin type insulators

With semi-conductive glaze on insulator head,our radio free pin type insulators is able to reduce the high electrical stresses and virtually eliminate corona discharges and radio interference. We currently offer low-, medium- and high-voltage pin type insulators that meet all ANSI standards.In ANSI standard,pin type insulators are normally defined as 55 series and 56 series,including: 55-1 […]

Porcelain shackle insulators

Shackle insulator is also called spool insulators,consisting of one component of insulating material and intended to be secured to the structure by means of a spindle passing through it. Contune International produce shackle insulators to ANSI standard and BS,the common products are: 53-1 shackle insulators,53-2 shackle insulators,53-3 shackle insulators,53-4 shackle insulators.

Toughen glass disc insulators

Toughen glass insulators supplied by Contune International is disc type insulators. These glass insulators has ball and socket coupling,designed and tested according to IEC standard. The common types we supply are: U70BS,U70BL,U70BSP,U70BLP,U120BS,U120BL,U120BSP,U120BLP,U160BS,U160BL,U160BSP,U160BLP. Disc glass insulators are connected to make a string used on power lines,with one end connected to poles by fittings and other end […]

Porcelain disc insulators

Porcelain disc insulators are made into disc shape,that’s why it got this name.The disc insulator has metal fittings on both ends,usually seen as ball and socket type,and also there are tongue and clevis type coupling. Several pieces of ceramic disc insulators are connected together to make up a insulator string.This string are used in electricity […]
