The OPGW/ADSS fitting assembly fabricated by Shenyang Tronco Electric is in accordance with  on IEC61284 standard. All iron and steel parts of the fittings are hot dip galvanized, in accordance with the international standard ISO1461.

DEADEND SET/TENSION ASSEMBLY

The helical formed wire inner and outer layer components are designed to transfer axial tensile loads and distribute radial compressive forces over the surface in contact with the OPGW to minimize effects on the central core and internal optical fibers. The inside of inner and outer rods covered with silicon carbide, increasing frictional force and damping effects. Minimum holding strength of dead-end set not less than 95% RTS of cable. Excellent anti-fatigue characteristic. The installation is convenient, no special tools needed.

SUSPENSION SET

For suspension towers, OPGW shall be suspended through an assembly with suspension clamp that will be free to swing in any direction. Inside of suspension clamp, at suspension point, shall be included proper material–neoprene–for the protection of OPGW and also at each clamp can be included proper set of preformed armor rods made from aluminum alloy. Armor rods are required to protect the conductor at suspension point. Assembly has to secure the direct electrical connection between OPGW and tower, as well as, the safe operation of fibers.

In each assembly shall be included all necessary fittings to attach the OPGW to the existing tower fitting. The breaking strength (U.T.S) of the assembly shall be deisgned according to the specifications.

AMOR ROD & VIBRATION DAMPER 

To avoid the surface of OPGW damaged by vibration damper clamp, the armor rods are assembled together with damper on OPGW.

The weights of vibration damper are different, small one and large one. This type damper has 4 resonant frequencies from 6HZ to 120HZ, allowing the dampers to be effective across a much wider frequency range than standard Stockbridge dampers. Connection weights with messenger cable by glue, offering better damper effectiveness and working life. Vibration dampers can be of the stockbridge type and proper to protect OPGW from aeolian vibrations.

OPGW JOINT BOX

The shell is made of high density aluminum alloy The jointing parts and fixing parts are made of high quality stainless steel and cast steel Repeated used, easy to re-joint and expand capacity Installed on tower or pole alternative Good mechanical, sealing and anti-corrosion performance Straight through or branched splice application, has 1 in 1 out, 1 in 2 out, 2 in 2 out function.
