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 […]
Insulators are important items in electrical power lines, they are widely used in all circuits and electrical or electronic systems to isolate electricity between two conductive materials. What we talk about today are polymer insulators and porcelain insulators applied on high voltage overhead lines. What’s the difference between polymer insulators and porcelain insulators? First of […]
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 […]
What is porosity testing machine? The porcelain shell porosity testing machine is mainly applied for testing the porosity of the porcelain insulator shell. Porcelain insulator tester, porcelain insulator testing machine, ceramic insulator testing machine,ceramic insulator tester,disc insulator tester Why do we need a porcelain porosity testing machine? To ensure the desired performance of an electrical […]
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.
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 […]
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 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 […]
