Product Overview
About PLB Duct
Godfill PLB Duct pipes are manufactured from HDPE with a permanently lubricated inner bore specifically designed for the smooth installation of optical fibre and telecom cables by blowing or pulling methods. Compliant with TEC (Telecommunication Engineering Centre) specifications GR/S/CAB-02/02, these ducts are available in OD/ID configurations from 25/20 mm to 50/42 mm. The ribbed outer surface provides extra stiffness for trench burial while the smooth coated inner bore minimises cable friction.
Key Features
- TEC GR/S/CAB-02/02 compliant
- Permanently lubricated inner bore (silicon coated)
- Ribbed outer surface for burial stiffness
- Low friction coefficient for cable blowing
- UV stabilised HDPE material
- Continuous lengths available (reduce joints)
- Available in coil and straight lengths
- Chemical and moisture resistant
