HT (High Tension) and LT (Low Tension) fittings are essential components in power distribution networks. HT fittings are designed to handle high-voltage electrical systems, while LT fittings are used for lower voltage applications. These fittings ensure secure connections, efficient power transmission, and reliable performance in various electrical installations. They are crucial for maintaining the safety and integrity of power systems, preventing electrical faults, and ensuring consistent power delivery to end-users.
