Type No.:MAG-35kV load break elbow THE-35
35kV underground elbow connectors provide utilities with products having high reliability and low maintenance expense.
These connectors provide:
Standard elbow and bushing loadbreak principle
Molded shields
Peroxide-cured EPDM compounds
Purple cuffs for quick 35kV identification
The separable elbow connector is 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 provide's superior elastomer stress relaxation characteristics under
high ambient temperatures and contributes to reliable, long-time operation in either above-ground or subsurface installations.
Elbow connector/integral bushing combinations are suitable for energized loadmake/loadbreak operations by a qualified
lineman using an shotgun-type hot stick. All elbow/integral bushing combinations are designed for use with subsurface or
padmounted installations.
