PRODUCT SHORT DESCRIPTION
JGH aluminum single-core HV cable cleat / clamp for rigid cable support in tunnels and substations. Non-magnetic alloy, secure bolted grip, short-circuit rated, corrosion-resistant.

PRODUCT DESCRIPTION

The JGH aluminum single-core cable cleat is a heavy-duty cable support fitting used to secure high-voltage single-core power cables in cable tunnels, substations, industrial plants and riser shafts. The cleat is machined or cast from high-strength, non-magnetic aluminum alloy, which avoids the eddy-current heating that occurs when magnetic clamps surround single-core AC cables. A two-part body with bolts clamps the cable firmly at set intervals, holding it against the electromagnetic forces generated during a short circuit while allowing thermal expansion. The result is a secure, code-compliant and corrosion-resistant cable fixing.

Key Features
• Non-Magnetic Alloy — Aluminum body eliminates eddy-current heating around single-core AC cables.
• Short-Circuit Withstand — Rigid clamp holds the cable against electromagnetic fault forces between supports.
• Single-Core HV Design — Purpose-built for securing one HV single-core power cable per cleat.
• Secure Bolted Grip — Two-part body and bolts provide a firm, even clamping force without crushing.
• Thermal Expansion Friendly — Controlled clearance lets the cable expand and contract under load cycling.
• Corrosion Resistant — Aluminum alloy and plated hardware suit damp tunnels and outdoor environments.
• Easy Installation — Mounts to ladder, tray, wall or structure with standard bolts; fast to fit in runs.
• Standards-Based — Designed to cable-cleat short-circuit and fixing requirements (IEC 61914 oriented).
