Whether you require inspection and testing, new equipment or technical advice, YHWH has the expertise to fulfil your needs.

  • CABLE includes a conductor and insulation, and is suitable for being run underground or underwater. This is in contrast to a conductor, which does not have insulation. High-voltage cables of differing types have a variety of applications in instruments, ignition systems, and AC and DC power transmission. In all applications, the insulation of the cable must not deteriorate due to the high-voltage stress, ozone produced by electric. We can provide you with:

  • Testing
  • Termination & jointing

  • Discharges in air, or tracking. The cable system must prevent contact of the high-voltage conductor with other objects or persons, and must contain and control leakage current. Cable joints and terminals must be designed to control the high-voltage stress to prevent breakdown of the insulation. Often a high-voltage cable will have a metallic shield layer over the insulation, connected to the ground and designed to equalize the dielectric stress on the insulation layer.
