Installation Steps
Pre-Installation Preparation
Inspect the cable for any physical damage before installation.
Verify that the cable specifications match the project requirements.
Calculate the cable routing to prevent excessive bending, which could impact its lifespan.
Laying Methods
Buried Installation: Dig a proper cable trench and use sand bedding and protective covers to prevent mechanical damage.
Conduit Installation: Use standard-compliant cable conduits and ensure they are free from sharp edges to avoid damaging the cable.
Cable Tray Installation: Secure the cable properly on the cable tray with fasteners to prevent movement or sagging.
Cable Connection and Grounding
Use appropriate connectors to ensure secure and low-resistance cable joints.
Properly ground the cable’s shielding and metallic sheath according to regulations for enhanced safety.
Inspection and Testing
Conduct insulation resistance tests after installation to ensure compliance with standards.
Check all fastening points to prevent loose or damaged sections.
Perform a power-on test to monitor voltage, current, and other parameters for stable operation.
