It features a built-in positioning and anti-detachment structure that automatically locks the interface after it is installed in place, preventing it from loosening or falling off during operation; it also features a built-in grounding connection structure that enables reliable grounding, effectively releasing induced voltage and fault current, and improving system safety.
With a fully insulated protective design and high outer insulation strength, the outer casing can be directly touched during operation without the risk of electric shock, ensuring the safety of maintenance personnel.

3. Odolnosť voči životnému prostrediu a poveternostným vplyvom

With excellent weather resistance, it can adapt to a wide temperature range of -40℃ to +90℃. The performance of conductive contacts and insulating parts does not degrade under high and low temperatures, and there is no risk of cracking or embrittlement. It is suitable for various outdoor and indoor operating scenarios.
Moisture-proof, waterproof, stain-proof, and salt spray-proof, with an IP67 protection rating, it can operate stably for a long time in harsh environments such as humid, dusty, and salt spray conditions, and is not afraid of rain or condensation.
Anti-aging and corrosion resistant, the conductive contact surface is tin-plated/silver-plated to prevent oxidation and corrosion, and the insulating parts are made of weather-resistant materials, with a service life of more than 10 years. It is maintenance-free and reduces the cost of later operation and maintenance.
