25kV Modified Polyethylene HDPE Pin Type Insulation Device
Description:
About the HDPE Pin Type insulation device
Also called Modified polyethylene pin insulator which is suitable for high voltage line facilities.It's made up of HDPE pin insulator,HDPE pin(spindle),colligation tie.
Everything is made of hard material.
It's has good heat resistance and cold resistance,good chemical stability,high rigidity and toughness, good mechanical strength,very good electrical performance,especially high insulation dielectric strength.The top and the bottom are the same installation size as the porcelain pin insulator which can be interchangeable with porcelain pin insulator.It's a new material for transmission line.Mainly applied in electrical syetem of 15kv,25kv,35kv and 65kV.
WE ARE NUMBER ONE IN CHINA!

OUR HDPE INSULATOR INSTALLED IN THE LAND OF CHINA IN 2015!
Our products Testing Report
In April 2017, the horizontal drop testing site
Test method: A 110kV length of 1240mm polymerized silicon insulator is free fall from a height of 7 meters.
Testing Results: The appearance of the product was free from cracking and brittleness, and the tensile failure test passed the standard requirements.
Please see the photos below:
In November 2017, it fell vertically to the test site.
Test method:110kV rod-shaped suspension polymerized silicon insulator was dropped vertically from a height of seven meters with the ball socket facing down. After the fall, checking if the seals at both ends of the fittings are sealed, and whether the entire insulator is intact. Then continue to pull, test, and achieve damage.
Testing results:
After the insulator falls, there is no damage at the seals at both ends. When the tensile force test reaches 150kN, the metal fitting of the ball is broken and the insulator is intact.
Please see the photos below:
Inductor center bending test in December 2017
Testing method: The rod-shaped suspension polymerized silicon insulator was pulled up 6 times with a vertical center pulling force. After pulling, check whether the entire insulator is intact. Whether the key area is pulled, broken, broken, or dropped. A 42-hour boiled test was carried out after 6 bends, and a lightning shock steep slope test was carried out after the boiled test.
Testing Result: There is no breakage or blockage after the insulator is boiled, and the lightning impulse meets the requirements of GB standard.
