HEX Bell Mouth Copper Cable Lugs – Crimping Type, 10 to 240 sq mm

HEX bell mouth copper cable lugs (BHT) have a flared barrel entry. The bell mouth guides every strand into the barrel quickly and prevents the outer strands from catching or splaying — especially useful with flexible and fine-stranded conductors. They are crimping-type E-copper tubular lugs, electro-tinned, from 10 to 240 sq mm; larger bell-mouth sizes are made on request. 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).

• Economy range — the same job for 35–1000 mm² where a lighter lug is acceptable.
• Bell mouth (this page) — 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.
