HEX Tubular Compression Copper Cable Lugs & Long Barrel Connectors – up to 33 kV, 6 to 1000 sq mm

HEX tubular compression copper cable lugs (HUTD) are heavy-duty compression terminals for cables up to 33 kV, from 6 to 1000 sq mm. Matching long-barrel compression connectors (HUTD-C) join cables from 25 to 1000 sq mm. Both are E-copper, supplied plain (uncoated) or electro-tinned. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

Which HEX copper lug do I need?

• Standard UL-listed tubular lugs — the general-purpose copper lug, 1.5–1000 mm², with inspection hole.
• Economy range — the same job for 35–1000 mm² where a lighter lug is acceptable.
• Bell mouth — flared entry for fast insertion of flexible or fine-stranded conductors.
• Without inspection hole — sealed barrel for damp or outdoor locations.
• Long barrel, 2-hole or 4-hole — longer crimp or anti-rotation palm for heavy terminations.
• 33 kV terminals — for HV cable terminations.
