Renewable Energy & BESS Wire Harness Solutions
Cablum manufactures custom wire harnesses and cable assemblies for solar equipment, wind systems and battery energy storage applications. Materials, voltage requirements, environmental protection and service-life expectations are reviewed against each customer-approved specification.
Designed for Project-Specified Service Conditions
Renewable-energy equipment can face UV exposure, moisture, temperature change and demanding electrical loads. Cable construction, materials and verification requirements are selected according to the customer-approved application specification.
UV & Environmental Material Options
XLPE and other jacket options can be reviewed for the specified environment.
High Voltage DC
Conductor, insulation and connector requirements are matched to the customer-specified operating voltage.
Torsion Resistant
Cable construction and routing can be reviewed for defined torsion or movement requirements.
Flame Retardant
Flame-retardant material requirements can be supported when specified and documented.
Testing Defined Around Your Energy Project
Verification scope is established from the approved drawing, electrical requirements and acceptance criteria rather than assumed as a universal specification.
- Continuity and wiring verification
- Visual and dimensional inspection
- Customer-defined electrical test requirements
- Controlled inspection records and revision traceability
