HOT SET TESTER AND ELECTRICAL TESTERS

Elastocon design and manufactures instruments for hot set testing of cable material according to IEC 811-2-1, and also according to IEC 60811-507 and other technically equivalent standards.

Elastocon also manufactures testing equipment for measurement of the electrical conductivity or resistance in rubber or plastic material for cables.

Rubber polymers are naturally electrical insulators and rubber is also used in many applications as insulation materials for electrical cables. When carbon black is compounded in the rubber, it increases the electrical conductivity and the rubber becomes a semi-conductor. With adding of special types of carbon black, the rubber can change to be more conductive.

Several different methods had been developed to determine the electrical conductivity or resistance. In principle, a voltage is applied across a rubber sample and the electrical current, which passes through the rubber, is measured. This may appear uncomplicated, but in actual fact, it is challenging to achieve in practice due to normally very small currents need to be detected. Furthermore, the resistance of rubber changes with temperature, time of electric exposure and physical stress.

The Yasuda Seiki No. 199 Volt Endurance and Destruction Tester is a high-voltage tester that is used to measure the electrical breakdown strength of materials. It is widely used in the electronics industry to test the quality of insulation materials, such as enameled wire, printed circuit boards, and transformers.

The Yasuda No. 173-S Cut-Through Tester precisely determines the temperature at which enameled wire softens using the cross-over method
