Cable Pulling Calculations

We deliver precise engineering calculations for safe and efficient cable installation across complex routes. Our services include:

Winch & Drum Sizing

Specification of pulling equipment, winch capacity, and drum dimensions based on calculated pulling forces and cable characteristics

Coefficient of Friction & Lubrication Strategy

Determination of friction coefficients for different duct materials and selection of appropriate lubricants to reduce pulling tension.

Route Optimization & Bend Radius Verification

Assessment of cable path geometry, including bends, elevation changes, and duct configurations, to ensure minimum bend radius and mechanical integrity.

Dynamic & Static Load Scenarios

Modeling of installation under varying conditions—straight pulls, multiple bends, and intermediate assist points—to ensure safe handling.

Compliance & Standards

Calculations aligned with IEEE 576, IEC 60287, and utility-specific requirements for installation safety and reliability.

Our expertise covers HV, EHV, and HVDC cable systems, ensuring installation integrity for underground, tunnel, and subsea routes.

Cable pulling calculations are essential for oil-filled cable installations. Discover our Oil Cable Design Services.
