600/900A Deadbreak Elbow
Product Overview
The 600/900A Deadbreak Elbow is a commonly used medium voltage (MV) cable accessory for 35kV and below applications. It provides a safe and reliable deadbreak connection for switchgear, transformers, and loadbreak devices. Designed with a cold shrink interface, it allows for quick installation without heat, ensuring long-term insulation and mechanical performance. The Deadbreak Elbow is fully shielded and features a bolted connection in either aluminum (600A) or copper (900A). Accessories are available for insulating, testing, grounding and circuit expansion.Applications
