The Loadbreak Elbow Connector is a fully shielded and insulated termination for connecting underground cable to transformers, switchgear, and other apparatus equipped with loadbreak bushings, junctions, or other loadbreak connectors.
The loadbreak elbow meets all the requirements of lEEE Standard 386 and is fully interchangeable with competitor's products and mating products that also meet lEEE Standard 386.
Tests conducted in accordance with IEEE/ANSI Standard 386
· Partial discharge minimum extinction voltage - 19kV
· AC 60Hz for 1min(kV crest) - 54kV
1. LOADBREAK PROBE
Tin plated copper probe with, arc extinguishing tip, allows for dependable switching operations.
2. SEMICONDUCTING SHIELD
Precision molded peroxide cured semiconducting shield provides ground shield continuity and meets the requirements of lEEE Standard 592.
3. SEMICONDUCTING INSERT
Precision molded peroxide cured semiconducting insert provides corona-free electrostatic shielding of the compression connector.
4. INSULATION LAYER
High quality peroxide cured EPDM Insulation is mixed and formulated in-house for complete control of rubber characteristics.
5. PULLING EYE
Stainless steel pulling eye for hot stick switching operations.
6. CESSION CONNECTOR
Standard Bi-Metal, or optional Copper, compression connector is sized to ensure a cool running connection with maximum current transfer.
7. CAPACITIVE TEST POINT
Capacitive test point on molded Elbow with snap-on cap provides a shielded, hot stick operable means to determine circuit condition.
8. DRAIN WIRE TAB
Drain wire tabs provide a convenient point to connect drain wire to ensure grounding of the connector shield.
