Low Voltage channel consists of three (3) types, namely Air Line Low Voltage (SUTR), Low Voltage Cable Channels (SKUTR), and the Land of Low Voltage Cable Channels. Air Line Low Voltage (SUTR) with LVTC (Low Voltage Cable Twistad), today has been developed, it is to enhance the reliability, safety and others. For this LVTC cable installation, 1) under SUTM (Underbuilt) and 2) special LVTC (pure JTR).
Accesoreis twisted cable consists of:
1. Suspension assembly
2. Large angle assembly
3. Dead end assembly
4. Insulated tap connector various sizes
5. Insulated joint Nontension
6. Insulated joint tension.
7. Guy sets / stay set SUTR
Use of guy set on SUTR use mild type, the stay set SUTR guy is not using insulators. Material specifications guy set in accordance with the standard image, are as follows galvanisnya steel wire. :
1. Ultimate load: 17 kN
2. Cross-section: 22 mm2
3. Material: Steel
Air Duct installation, the conductor must be drawn is not too tight and should also not be too loose, so that the conductor does not suffer mechanical damage and fatigue due to the pull and swing, on the other hand the use of savings achieved conductor.
In cabling air after standing pole, while holding the cable of haspel first mounted auxiliary equipment (clamps service), binders, holders and so on. For insulated conductor cable, part of which was tied to a pole holder is conductive Zero, both for the two wires (one-phase system) or four wires (three-phase system).
Withdrawal cable starts at one end of the pole, then pulled the tensioning tool (hand tracker. After pulling considered strong enough, then at each pole Zero cable tied with the holder has been prepared.
