The B Strand Ground Clamp secures cable sheath, bonding ribbon, or ground wire to messenger strand in electrical and telecommunication installations. It establishes a reliable electrical connection for fault current dissipation and system safety in overhead transmission lines.
An internal self-seating compression plate distributes clamping pressure evenly along the strand, ensuring a secure, vibration-resistant connection. Constructed from steel and hot dip galvanized per American Society for Testing and Materials (ASTM) Specification A153, it provides corrosion resistance. The clamp accommodates strand sizes from 3/16 inch to 1/2 inch and includes a 1/2 inch by 1-1/2 inch square head machine bolt with a 1/2-13 regular square nut for assembly.
Installation requires positioning the clamp on the strand, tightening the bolt to achieve steady clamping pressure, and verifying electrical continuity. Maintenance includes periodic inspection for physical damage, corrosion, or loose fasteners, with retightening and cleaning as needed to maintain a low-resistance path.
The clamp complies with ASTM A153 for galvanization and Bellcore specification 7182, meeting recognized safety and performance criteria. Its corrosion-resistant materials enable adaptability to moist environments while maintaining compatibility across various strand and cable sizes.
