Powertech’s laboratories provide testing of separable insulated connectors.

Separable insulated connectors are used in medium- to high-voltage electrical systems for attaching cables to equipment and joining cables together. They provide simple, inexpensive connection and switching to transformers, switchgears, and other equipment used in substation-to-underground electric distribution, renewable energy, rail, mining, oil and gas, and other industries. Separable insulated connectors are key elements in today’s rapid expansion of underground distribution systems.

Powertech provides testing of various types of separable insulated connectors, including:

  • Elbow
  • Bushing insert
  • Cable joint
  • Tee connector
  • Bushing well
