Large Bending Torsion Testing Machine 21M Long Delivered Successfully
Post insulators for large power stations are often of considerable height, requiring professional testing equipment to ensure their quality and safety. Today, our company successfully delivered a large torsion bending testing machine, which is specially designed to meet the quality inspection needs of such high post insulators. This large-scale testing machine boasts impressive specifications: with […]
Difference between polymer insulators and porcelain insulators
In the field of overhead transmission lines, insulators are core components that ensure insulation performance and mechanical stability. Among the various types of insulators widely used in power systems, polymer insulators (also called composite insulators) and porcelain insulators (traditional ceramic insulators) are the two most common options. While both serve the basic function of isolating [...]

Combined Electrical&Mechanical Test on insulators
Combined Electrical & Mechanical Test is an important test on high voltage porcelain disc insulators. In ANSI and IEC requirements, the disc insulator is mounted in a tensile testing machine with both ends connected. On the both ends, there is a voltage applied. This artical is embedded with a video of Combined Electrical & Mechanical […]
Porcelain Post Insulators
Porcelain post insulators are widely used on electrical power substation and transmission line systems. In the substation line system, post insulators are commonly seen as station post insulators. On both sides of the station post insulator, there are flanges with drilled holes for bolts fixing. These station post insulators are fixed on the bottom base […]
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.
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 […]
