Structural Features:

The enclosure structure is available in vertical and horizontal configurations. The outer shell is made of 2mm stainless steel plate formed through multiple folding processes (or using a honeycomb-structured stainless steel double-layer composite panel, which offers flame-retardant, environmentally friendly, thermal insulation, and anti-condensation properties). Special stainless steel welding techniques are employed, resulting in high overall structural strength after enclosure fabrication, with a mirror-like smooth surface free of welding marks; The internal mounting beams (plates) are treated with a thermal curing process to ensure no corrosion for 20 years; The enclosure has front and rear doors for easy user operation and maintenance. The door edges are fitted with high-elasticity, weather-resistant sealing strips. Each door is equipped with two types of locks: a visible lock and a hidden lock, with the visible lock featuring a rainproof cover to prevent blockage and rust; The metering chamber is fully enclosed with a lead seal device; the sides of the enclosure are fitted with rainproof and debris-proof cable entry conduits. The bottom is perforated with ventilation holes and electrical outlet holes, while the top lacks ventilation ducts and mesh, providing waterproof, rustproof, debris-proof, and anti-corrosion functionality. Protection rating: IP54.
