Twin track accordingly finalizes its design of porcelain housings in consultation with the manufacturers of equipments so as to meet the electrical and mechanical requirements, fixing and sealing arrangements and dimensional needs of an electrical equipment within the manufacturing possibilities of shape, size and dimensional tolerance of large hollow porcelains commensurate with provisions of IS 5621-1980.Twin track apparatus porcelains are subjected to tests specified under IEC-233/IS 5621-1980. Special Mechanical and Hydraulic tests are also carried out as many be prescribed by the equipment manufacturers.
