Test Terminals Made of Lightweight Aluminum

PCORE Electric Company, Inc. has launched an extension of its test terminal product line manufactured from lightweight aluminum.

PCORE Test Terminals allow utilities to perform field dielectric tests of substation equipment such as transformers and circuit breakers faster, safer and at a substantial savings to alternative testing methods.

The Test Terminal functions as an electrical switch permanently connected in series between the power bus and the equipment to be tested, eliminating the need to physically remove the power bus during testing. After de-energizing the power bus, substation personnel need only loosen a total of eight captive bolts on the Test Terminal allowing the Terminal’s blades to swing out into an open position. With the blades open, the power bus is grounded and the equipment is isolated and ready to be tested.

Currently available in four styles and rated at currents up to 2500 A, the aluminum test terminals provide the same convenience as the existing copper models but do so at a weight that is as much as 55% less than the copper equivalent, depending on the specific model.

PCORE Electric Company, Inc. provides capacitance graded bushings, related components, diagnostic services, and repairs to the electric utility industry and its equipment suppliers. Designed and manufactured under the company’s ISO-9001 Quality Program, PCORE products are applied around the world on power generators, transformers, circuit breakers, and substations.
