Silicone rubbr material for 33KV polymer insulators

Silicon rubber is the material of the external insulation of polymer insulators. This silicon rubber material is for 33kV OHTL polymer insulators.

Anti Spy Detector for hidden camera,GPS trackers

Anti Spy Detector is a very useful detecting device for GPS trackers, hidden cameras, wireless audio bugs and many other forms of surveillance devices. Users may carry in hand with travel or living in a hotel or Airbnb to check if there are hidden cameras or other spying devices for security inspection.

33kV Composite Pin Insulators

33KV composite pin insulators are used on 33KV high voltage overhead power distribution lines. These pin insulators are made by FRP core, silicon rubber, and metallic fittings. On the bottom side of the fitting, it is where we call pin, the pin has a screw which is used to fix the insulator onto the cross-arm. On header fitting, it usually has a groove shape to fix conductors.


Crimping machine is applied in the production line of high voltage composite insulators. The model no.CTCPM-140 is available for insulators with voltage from 11kV to 33kV, including all types of composite insulators.

Insulator FRP core oil puncture test machine

This testing machine provides a sample test for polymer insulators, it is applied to test the electrical puncture voltage of fiberglass core (FRP/ECR rod) of polymer insulators.

Insulators Cantilever & Torsion Test Machine

Cantilever & torsion test equipment is used for the mechanical bending test and the torsion test of post insulators according to the test methods and acceptance criteria of technical standard IEC 61109 and IEC 60383.

Acoustic Emission System for Insulator Crimping

The acoustic emission detecting system helps to detect the cracking noise of FRP core during the crimping of insulator fittings. It's used in the production line of insulators.

Electrical power frequency test device

Test equipment for electrical tests pm overhead line insulators. This test machine tests high voltage insulators with power voltage and frequency. The power frequency tests are required in IEC, ANSI or any other technical standards for insulators of OHTL.

Tracking & Erosion Tester of Composite Insulators

Tracking & Erosion tester is used for tests of silicon rubber shed and housing of electrical polymeric insulators. It is to test the anti-tracking and erosion ability of its silicon rubber material as per IEC or DIN EN standard.

Laser Marking Machine For Composite Insulators

Laser marking machine is applied in marking words, logo, symbol, character and etc on multi-material items. It has advantage of wide adaptability, fast speed and high precision.
