Installation

1. Without any special tools.

2. When finish the installation of elbow connector, the power can be supply directly.

3. Can be used together with the bushing, cable connector and junction witch meet the requirement EN50180/EN50181DIN47636/HN52-S-61.

Product Structure

1. Conducting Rod:Tin-plated copper pin screws into the conductor contact with the supplied hex key.

2. SEMI-CONDUCTIVE INSERT: Moulded EPDM conducting rubber screen controls electrical stress.

3. Insulation: Moulded EPDM insulating rubber is formulated and mixed in-house to ensure high quality.

4. Pulling Eye: Encapsulated stainless steel pulling eye with a detent to position the bail.

5. Capacitive Test Point: Capacitive test point provides means to check circuit status. A moulded EPDM conducting rubber cap provides a watertight seal.

6. Stress Relief:The configuration of the outer screen and the cable adapter provide cable stress relief.

7. Cable Adapter: The sized opening provides an interference fit to maintain a watertight seal.

8. Grounding Eye: Moulded into the external screen for connection of an earthing wire.

9. SEMI-CONDUCTIVE SHIELD:Moulded EPDM conducting rubber mates with the cable screen to maintain screen continuity and ensure that the assembly is at earth potential.

10. Conductor Cable lug: Inertia welded bimetallic compression connector accepts copper or aluminum conductors.
