GENERAL INFORMATION

Hubbell 8.3/14.4 kV underground connectors provide utilities with products having high reliability and low maintenance expense.

These connectors provide:

  • 10,000-amp fault-closing capability
  • Piston-operated fault-close action
  • Standard elbow and bushing insert loadbreak principle
  • 1/8" thick Molded shields
  • Peroxide-cured EPDM compounds
  • Full compliance with IEEE Standard 386

Hubbell separable connector bushing inserts and elbows are designed for use with single-conductor, concentric neutral power cable having extruded insulation shielding. With shield adapter products, the elbow can be used with cables having a metallic tape shield, wire shield, or lead sheath with tape or extruded insulation shielding.

All insulating and conducting rubber components are made of a special formulation of an EPDM elastomer using a peroxide curing process. The material and curing process provides superior elastomer stress relaxation characteristics under high ambient temperatures and contributes to reliable, long-time operation in either aboveground or subsurface installations.

Elbow connector/bushing insert combinations are suitable for energized loadmake/loadbreak operations by a qualified lineman using an 8’ shotgun-type hot stick.

All elbow/bushing insert combinations are designed for use with subsurface (submersible to 6 feet of water) or pad-mounted installations.

Where to Use

Hubbell 15 kV loadbreak products are designed for operation on and connection to 15 kV class, 95 kV BIL systems where the voltage ratings listed on this page are not exceeded.
