PLB HDPE Ducts
We manufacture PLB HDPE Duct as per TEC/GR/FA/CDS-008/04/AUG-19 of BSNL
CONSTRUCTION : Permanently Lubricated HDPE Ducts (PLB HDPE Duct) are formed by co extrusion technique and are used for laying Optical Fiber Cables as underground ducting / conduits.
MATERIAL : The base raw material being used for the manufacturing Permanently Lubricated Ducts is High Density Poly Ethylene. The grade of raw material is ultra violet grade and is confirming to IS:7328-1992 & IS : 2523 or ISO : 1183 & ISO : 1133 and is designated as PEELA-50T-012 (CACT Approved) and inner layer permanently lubricated material DOW CORNING Grade-50MB002.
APPLICATIONS : Telecommunication, Computer Network, Automatic Signaling, Railways Information Network. Highways, Cable Service Providers, Broad Band networks, Electric cable installation etc.
FEATURES
- Reduction of stress on cable during installation.
- Installation of Longer lengths made feasible.
- Negotiations of cable movement through bends and deflections are easier.
- Reduction of number of joints and minimizes number of splices.
- Faster and easy installation of cable with lesser man power.
- Reduction of overall cost of installation, maintenance and future upgrades.
- Retains its properties throughout its life.
- Existing cables can be deployed after de-blowing from the duct.
- This does not have toxic and dermatic hazards and is safe handling.
