What is “Insulator bending & torsion resistance testing Machine”? The bending torsion testing machine is mainly applicable in the mechanical bending (cantilever) and torsion test for post type insulators and pin type insulators with material of porcelain and polymer. As it is required in IEC standard and ANSI standard, porcelain post insulators for subsation and overhead […]
The thermal state bending test machine is applied in testing the three point bending properties of round bar specimen under the thermal environment.
Insulator Machine: Insulator tensile testing machine (Also known as insulator tensile tester/tensile machine/tension test machine/tension tester/pulling machine /insulator strain machine/tensile tester for high voltage electrical insualtor) What is “insulator tensile testing machine” (insulator tensile tester) Insulator tensile testing machine is designed to perform mechanical property tests (tensile tests) of various types of steel wires, cables, […]
WHAT IS “INSULATOR LOCKING PIN TESTING MACHINE”? This locking device testing machine supplied by Contune Intl company is designed to test locking device(retaining pin) on insulators. WHY SHOULD WE USE “INSULATOR LOCKING PIN TESTING MACHINE”? HOW DOES IT PERFORM THE “LOCKING PIN SPLITTING TEST”? In many overseas projects,disc insulators of ceramic material or toughened […]
Contune International supply metal accessories for overhead lines,including transmission line,power distribution line and substation line. Our line accessories are mainly conform with IEC standard or Australia Standard. Material of our line fittings are steel ,stainless steel and aluminum or copper. For the steel items,they are all hot dip galvanized for anti-erosion. The oh-line accessories supplied […]
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 […]
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.
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 […]
