Aluminum Metal Joint Box For OPGW & ADSS Fiber Optic Splice Closure

The Wolon Metal Joint Box (Fiber Optic Splice Closure) is a heavy-duty, premium enclosure specifically engineered for the splicing and protection of OPGW (Optical Ground Wire) and ADSS (All-Dielectric Self-Supporting) fiber optic cables. Designed for deployment in high-voltage power transmission networks, this rugged dome-style closure provides a secure, weatherproof environment for critical optical connections on transmission towers and utility poles.

Constructed from high-strength aluminum alloy, the Wolon Metal Joint Box offers unparalleled resistance against mechanical impact, extreme temperature fluctuations, UV radiation, and severe weather conditions. Featuring a robust mechanical sealing system with multiple cable entry ports, it prevents moisture and dust ingress (IP68 rated), ensuring the long-term integrity of your fiber splices. Whether for new power grid communication lines or maintenance upgrades, this metallic closure guarantees carrier-grade reliability.

Industrial-Grade Aluminum Alloy: Manufactured from premium aluminum alloy, providing excellent mechanical strength, corrosion resistance, and shielding against electromagnetic interference in high-voltage environments.

OPGW & ADSS Compatible: Specifically designed with specialized cable entry ports and anchoring mechanisms to securely grip and seal heavy-duty OPGW and ADSS cables.

Exceptional Environmental Protection: Advanced mechanical sealing technology ensures a completely airtight and waterproof enclosure (typically IP68), protecting delicate bare fibers from rain, ice, and dust.

Spacious Splice Trays: The interior is equipped with high-capacity, stackable splice trays that manage fiber routing safely and maintain the required bend radius.

High Visibility Safety Design: Features a prominent red lightning bolt warning symbol on the exterior, instantly identifying it as power-line telecommunication equipment for safety compliance.

Tower & Pole Mountable: Comes with customized heavy-duty mounting brackets and stainless steel bands for secure installation on steel lattice towers or concrete poles.

Power Grid Communications: Essential for splicing OPGW cables running along the tops of high-voltage transmission towers.

ADSS Aerial Deployments: Protecting optical joints on distribution lines and utility poles where all-dielectric cables are used.

Harsh Environments: Ideal for mountainous regions, coastal areas, or industrial zones where standard plastic closures would degrade quickly.

Utility Network Expansions: Connecting main trunk optical lines to local distribution substations.
