PVC conduit is the lightest in weight compared to other conduit materials, and usually lower in cost than other forms of conduit. It is available in three different wall thicknesses, with the thin-wall variety only suitable for embedded use in concrete, and heavier grades suitable for direct burial and exposed work. The various fittings made for metal conduit are also made for PVC. The plastic material resists moisture and many corrosive substances, but since the tubing is non-conductive an extra bonding (grounding) conductor must be pulled into each conduit. PVC conduit may be heated and bent in the field. Joints to fittings are made with slip-on solvent-welded connections, which set up rapidly after assembly and attain full strength in about one day. Since slip-fit sections do not need to be rotated during assembly. Since PVC conduit has a higher thermal coefficient of expansion than other types, it must be mounted so as to allow for expansion and contraction of each run. Care should be taken when installing PVC underground in multiple or parallel run configurations due to mutual heating effect of cable.
KAWSAR offers a complete line of Electrical Conduit and Power Duct pipe products which include: Schedule 40 and 80 Conduit (NEMA TC-2, ANSI/UL651), Encased and Direct Burial Conduit (ASTM F512, NEMA TC-6 & 8 and/or ANSI/UL 651A), and Type C Telephone Duct. All KAWSAR Electrical Conduit and Power Duct pipe products are offered in 4 meters laying lengths (10 foot and 20 foot lengths are also manufactured on special order by customer. This means that more ground can be covered during installation while eliminating the cost of unnecessary joints.
KAWSAR Electrical products are suitable for a variety of utility uses, including gas transmission, power, utility, telephone, as well as telephone and fiber-optic non-pressurized applications. Products come in PVC and HDPE. PVC electrical fittings including elbows, sweeps, boxes, spacers and couplings are available to complement the line.
