In extremely humid environments such as rainforests in Africa, traditional lighting electrical ready boards often pose safety hazards such as electrical leakage and short circuits due to moisture, posing a serious threat to personnel life and equipment safety. The emergence of double-layer insulated lighting electrical ready boards provides a revolutionary solution to this problem and has become a key technology for ensuring electrical safety.

The double-layer insulation design provides dual protection through physical isolation and material innovation, creating a sturdy barrier against moisture. The outer layer is made of high-strength stainless steel or engineering plastic, with a waterproof rating of IP66 or above, which can effectively block rainwater infiltration; The inner layer is wrapped around electrical components with special insulation coatings or insulation materials to form a second layer of protection. This structure not only complies with the GB/T 4208-2017 standard for "Protection Class of Enclosures (IP Code)", but also passes the recommended alternating humidity test (40 ℃± 2 ℃, relative humidity 90% -100%, continuous for 6 days) in GB/T 14048.1-2023 "Low voltage switchgear and control equipment Part 1: General principles", ensuring stable operation under extreme humidity.

In practical applications, double-layer insulated electrical ready boards demonstrate significant advantages. In a research station project in the African rainforest, the traditional electrical ready board malfunctioned due to frequent moisture, requiring an average of three repairs per month; After switching to a double-layer insulated electrical ready board, the failure rate has been reduced to once a year and no leakage accidents have occurred. Its sealing structure, combined with silicone desiccant and humidity monitor, can maintain the humidity inside the box below 60% in real time, completely eliminating the risk of condensation. In addition, the double-layer design also integrates surge protectors (SPDs) and lightning protection grounding systems, forming a "waterproof moisture-proof lightning protection" three in one protection system, fully adapting to the complex climate of rainforests.

This innovation not only enhances the level of electrical safety, but also promotes the upgrading of industry standards. With the promotion of standards such as GB/T 15211-2013 "Requirements and Test Methods for Environmental Adaptability of Security and Alarm Equipment", double-layer insulation technology is becoming a standard for distribution equipment in humid places, providing reliable guarantee for power supply in extreme environments worldwide.
