Application Cases Of Waterproof Terminal Blocks In Harsh Environments

Waterproof terminal blocks, with their excellent protective performance, have demonstrated strong application value in harsh environments. The following are specific application cases:

1. Outdoor lighting system

Waterproof wiring terminals are the core components that ensure electrical safety in outdoor lighting equipment such as street lamps and landscape lights. For example, in a major road lighting renovation project in a certain city, before the use of waterproof terminals, short-circuit faults caused by water ingress into the lines occurred frequently during the rainy season, resulting in high maintenance costs. After adopting IP68 waterproof terminal blocks, its silicone sealing ring and integrated extruded sealing ring design effectively block rainwater intrusion, reduce the failure rate by 80%, and significantly improve the reliability of night lighting. In coastal typhoon prone areas, such terminals can withstand short-term rainstorm immersion to ensure continuous operation of equipment.

2. Industrial production environment

In the chemical workshop, waterproof wiring terminals need to be resistant to corrosive gases and liquids. In the ethylene production unit of a petrochemical enterprise, stainless steel waterproof terminals are used to connect key equipment control circuits. Their chemical corrosion resistance and high protection level enable the terminals to operate stably in acidic gas environments for more than 5 years, avoiding production losses caused by connection failures. In the food and beverage processing workshop, waterproof terminals are made of food grade materials that meet hygiene standards, while preventing moisture infiltration during cleaning operations to ensure equipment safety.

3. In the field of new energy

In photovoltaic power generation systems, waterproof terminal blocks are used to connect solar panels to inverters. In desert areas, its high temperature resistance, UV resistance, and sealing structure effectively block sand and dust intrusion, ensuring power generation efficiency. In the wind power generation system, the waterproof terminals used in offshore wind turbines need to resist salt spray corrosion and strong wind invasion. A certain offshore wind farm uses terminals with special anti-corrosion treatment, which reduces the electrical circuit failure rate by 65% and ensures the stability of energy supply.
