The Cap Type Metal Joint Box houses and protects spliced ADSS (All-Dielectric Self-Supporting) and OPGW (Optical Ground Wire) fiber optic cable connections in electrical and telecommunications networks. Built from aluminum alloy and stainless steel, it delivers high mechanical strength and corrosion resistance for outdoor installations, with sealing rings and silicone providing protection against moisture, dust, UV rays, and environmental contaminants.
The cap-type design enables secure closure and tool-free access to internal optical fiber splice trays during maintenance. Vibration dampers and suspension clamps mitigate wind-induced stress, while the enclosure withstands operational temperatures from -40°C to +60°C, atmospheric pressure from 70 kPa to 106 kPa, and seismic activities. Tensile strength exceeds 2000 N, with sealing capabilities maintaining internal pressure stability and a service life beyond 25 years.
Applications include tower and pole installations at intermediate and terminal splicing points in overhead cable systems across telecommunications networks, data centers, and power distribution infrastructure. The joint box accommodates multiple cable configurations for network expansion and maintenance in environmentally challenging areas.
Installation uses cable storage shelves and mounting clamps, with all attachment components included. Quality assurance follows ISO9001:2008 certification standards, with testing protocols verifying sealing integrity, mechanical strength, and long-term durability across production batches.
