Main features of products
The pipe can bear 2,500 V voltage and avoid electric leakage and shock. Good fire resistance: The self-ignition flame on pipe can be knocked down quickly after leaving fire source, with oxygen index above 40, to avoid fire spreading along with pipe. With low heat conductivity, the pipe can be well protected in case of fire, to ensure normal functioning of electric control system and personnel evacuating.
Easy workability and handling:
Designed to be opened and closed repeatedly, the cover of exposed-paving flame-retardant plastic trunking can simplify the wiring and circuit change, and be easily handled for installation due to light weight. It can be sawn, cut or nailed, spliced or connected into the shapes needed using JHPI’s accessories.
High resistance to corrosion and insects:
Trunking is resistant to general acid and alkali and insect.
■Select the trunking and accessories as required, arrange the circuit on wall or ceiling in an exposed, concealed, horizontal, vertical, direct and indirect manner；
■Once trunking length is confirmed, cut it using a cutter and keep good smoothness and proper angle of fracture surface；
■Drill hole on wall, install the expansion pipe, trunking and ribbon, fix the screws, cross pipe and install the cover.
