Supports for high or medium voltage electrical conductors (6, 7) at potentials different from the potential of an enclosure (1) are supported by disc-shaped parts (4, 5) made from thermoplastic polyester, for example terephthalate polyethylene. The discs (4 and 5) provide good insulation without largely disturbing the electrical field around the conductors due to their fairly low dielectric constant. They are also compatible with use under SF6 gas.
