Copper closures are used to connect the copper conductors (up to 0.8 mm) of telecom cables. The conductors are connected with Picabond, a light-weight copper connector. It is made of tinned phosphor bronze and tin-plated brass with a polyester insulation. Around these connections for the XAGA model heat-shrinking wraparound and for the MJC-closure the gel-seal technology is applied. Infraconcepts loves to advise you on choosing the right copper closures.
Copper closures are applied in telecom-networks with copper cables. The XAGA heat-shrinking wraparound can be used on hanging cables, direct-buried, and telecom cables that are laid in pipes. These cables can also be connected to cables that are gel-filled, or dry (without gel), or to those that have a PE-coating, a lead coating, steel coating, or aluminium coating. Thanks to the frequently used shrinking technology of CommScope, a water-tight connection between the cables is created. A maximum of 3 cables can be installed on both ends, thanks to a special three-finger clip. The copper telecom-cable can be connected by a maximum of 800 pairs of copper connectors through the Picabond connector. This on condition the conductors are solid.
The MJC-closure can be used to connect hanging cables or direct-buried telecom cables. This closure has the advantage that no source of heat needs to be deployed to create water-tight connections. The gel-seal technology, combined with the cable-fixing system, helps to assure an IP68-certification. In the MJC-closure cables can be installed up to a total number of 100 pairs of copper conductors.
Thanks to the special Picabond-pliers conductors with various types of wire-insulation (for example paper, foamskin, PVC, or plastic) can be connected with one another without stripping or cutting. The connectors have colour-coding based on the conductor’s diameter.
