Long Rod Insulators Tensile Test machine

This testing machine is designed to perform mechanical property tests of long rod insulators, steel wires, cables, conductors, power fittings,chains, electrical devices, it's also available for mechanical property tensile tests on other specimen with long shape.

General Details

What is the tension test machine / horizontal tensile testing machine?

The long rod insulator tensile testing machine is applied to do mechanical tension/compression property tests of various types of steel wires, cables, conductors, chains, power fittings, electrical devices, insulators, and insulating materials, it’s also available for mechanical property tensile tests on other specimens with long shape.

The main testing machine has a horizontal structure, which makes sample assembling and disassembling easy. The tester consists of a main machine, servo loading system (servo motor and lead screw) and computer data processing system for analyzing test data, record and print. Application of computer technology makes test procedure simple and test data accurate, and it has functions of data processing, automatic curve drawing of testing force and testing time, storage and printing for the same.

As a high precision ratio control valve is adopted for a servo loading system to closely track and regulate the loading system, this tension testing machine can perform the continuous tests. Users could automatically make tests with preset loading requirements by only plating samples on the equipment.

What function does the long rod insulator tensile testing machine (horizontal) have?

The tester has functions for force testing, loading speed automatic tracking and measurement of loading speed and peak value protection. During the test of insulators, it has functions of overloading protection and displacement protection, test data can be automatically stored and test reports can be printed.

This tensile testing machine can be used for mechanical property tests and analysis of insulators for manufacturers and testing or research institutions.

What types of insulators can be tested with this long rod insulator tensile testing machine(horizontal type)?

This tension test machine is available for high voltage insulators with all types of material. For example, polymeric insulators tension and suspension type, ceramic disc insulators, toughen glass disc insulators

What voltage level of OHTL insulators does it apply on?

Insulators with voltage level from 11kV to 400KV.

What type of tests is this long rod insulator routine tester available for?

Regarding the type of tests, it can perform prototype test, type test, routine test, sample test and etc, which are commonly  seen in technical standards like IEC, ANSI, DIN, GB and so on.

What is the testing length of this insulator testing equipment?

Normally the regular types of this testing machine have valid test length of 3 meters, 5 meters or 10 meters. This length means the section length of a tension insulator, nor the machine’s overall length.

The valid testing length can be customized according to client’s specific demand.

What is the tension strength of this insulator testing machine? How much kilo newtons / tons?

Regular types has maximum tensile strength of 300kN, 500kN or 1000kN, which covers all common types of high voltage insulators, like 11KV disc insulators, 33kV polymeric insulators, 132kV/400kV suspension insulators of overhead transmission lines.

What type of insulators testing machine should I choose? Length? Strength?

This depends on user’s specific demand. Different type of insulators needs different length and test strength. For example, a composite tension insulator of 110kv usually has a section length of more than 1M and specified mechanical load of 70kN, then a testing machine with 3m valid testing length can test 2 pieces of such insulators at a time. And 300kN type is enough for it, even for breaking sample test.

For more information please contact us. We would recommend a suitable type of tester for each client.

  1. Can this test machine used for mechanical breaking load test of porcelain insulator? We need such test for 11kv disc insulators.

    • Yes, this insulator test machine is available for all mechanical tension sample tests on ceramic disc insulators, and available for routine tests too, which is 50% force value of SML.

  2. Very useful test equipment for tension insulators,we use it for mechanical routine test of 33kV composite insulators,thanks

    • Thanks for purchasing our machine, we also have other test machines of OHTL insulators for other mechanical tests and electrical tests.
