Description

General information:   GTKXX-1/2/3/4 SCC - ground wire corrosion-resistant;   EXAMPLE recording symbol SCC ground wire mark with a nominal diameter of 9.1 in its order and documentation of other products: "GTK20-0 / 50-9,1 / 60."   xx - type aluminum clad steel wire;   1 - section aluminum wires; 2 - cross section of the aluminum clad steel wire; 3 - SCC diameter, mm; 4 - mechanical tensile strength kN.   It is used as a lightning rod grounding Length of rope strung along the overhead power line, which serves to protect the conductive wires from direct lightning strikes. Grounding wire corrosion (SCC), intended for suspending on supports transmission lines 35 kV and higher. SCC are made of steel clad aluminum wires or aluminum-clad steel wires and wires of aluminum alloy.   SCC operated at an ambient temperature of minus 60 to plus 80 ° C with the solar radiation.   Benefits:   - clad wire can cause an emergency. All cable wire preformed so that in case of interruption of one or more wires are not weave from Helix.   - The load on the bearings. Weight clad steel cable less, which greatly reduces the load on the support. For the same tonnage with a steel cable, a clad cable is considerably larger in the mileage.   - High resistance to corrosion. All steel wire coated with aluminum, which is several times more effectively protects the steel from corrosion.   - High reliability. The bimetallic wire produced using plating technology, aluminum adheres to the steel at the molecular level, then even under strong mechanical action is impossible to remove the aluminum from the steel wire as a result can not be subject to corrosion due to violation of the cover.   - Resistance to high temperatures.   - Resistance to high short-circuit currents.   - Lifetime clad cable is 45 years old.   - clad ground wire racks to aeolian vibration and pitching.   - Easy installation. Clad cable is similar in overall dimensions of traditional cables, respectively, mounted in a standard clamp.
