Select the correct HT or LT cable type, size and voltage rating as per your electrical design and load calculations. Ensure power is fully isolated before installation. Lay cables along planned routes using proper trays, ducts or conduits. Maintain bend radius and spacing from heat sources. Use certified joints, terminations and earthing. Test insulation resistance and continuity before energising the system. Schedule periodic inspections for damage, loosening or overheating and replace worn sections promptly.

HT cables are designed for high voltage transmission, typically above 1 kV, and are used to carry power over longer distances with higher insulation requirements. LT cables operate at lower voltages, usually up to 1 kV, and are mainly used for local distribution and internal wiring in buildings and industrial systems.

HT and LT cables are widely used in industrial plants, commercial complexes, substations, power distribution networks and large residential projects. HT cables handle incoming high-voltage supply from utilities, while LT cables distribute power to machinery, lighting and equipment. They are suitable for both underground and overhead installations, depending on design requirements.

To select the correct ht and lt cables, consider load current, system voltage, installation method, ambient temperature and permissible voltage drop. Refer to cable sizing charts and relevant IS/IEC standards. It is recommended to consult a qualified electrical engineer who can calculate appropriate cross-sectional area for safe, efficient and future-proof operation.

Yes, many HT and LT cables are designed for underground installation with special insulation and outer sheathing to resist moisture, soil chemicals and mechanical stress. When laying underground, follow correct trench depth, sand bedding and protective covers. Proper jointing, sealing and testing ensure long service life and safe operation in buried conditions.

HT and LT cables require periodic inspection for insulation damage, discoloration, loose terminations and signs of overheating. Thermal scanning, insulation resistance tests and continuity checks help detect issues early. Keep cables clean, dry and protected from sharp edges or excessive bending. Any repairs or modifications should be performed only by qualified electrical professionals.
