Tubelec pipes - ULPI - The United Lebanese Plastic Industries

These pipes are designed for heavy duty (hd) applications. These conduits are intended to be used in electrical distribution systems inside buildings.

TUBELEC^® IRL 4431 1250 N /5cm

TUBELEC ^® Electrical conduits are manufactured in compliance with requirements of the European and Lebanese Standard NL- EN 61 386 (parts 1 & 21). Heavy Metal Free (RoHS). The text of the International Standard IEC 61386:2008was approved by CENELEC as a European Standard without any modification.

Main characteristics

Corrosion resistance: resistant to acids, bases and salts.
Light weight, ease of installation, ease of maintenance.
Non-conductive: good insulation, able to resist 25kV voltage.
Fire resistant: self extinguishing, do not support combustion.
Impact strength: resistant to compression and impact, can be buried in concrete.

Designation of standard conduits:
Conduits are designed according to their mechanical characteristics with a code:
3 or 4 letters +4 digits: ABCD XXXX
