PVC CONDUITS

Only virgin PVC goes into the making of konseal - offering better quality, better fire resistance and better shock resistance.

The Benefits and Safety of PVC & PVC Conduit's :-

  • Voltage resistance:- , PVC's resistance to breakdown under high electrical voltage and its ability to bend without cracking make it the leading material for conduits.
  • Strong and lightweight :- PVC conduit's abrasion resistance, lightweight property and good mechanical strength and toughness are key technical advantages for its use in wiring & cabling.
  • Fire Resistant :- Rigid PVC conduit is inherently difficult to ignite and stops burning once the source of heat is removed. This makes it particularly suitable for electrical wiring.
  • Durable :- PVC conduits are resistant to weathering, chemical rotting, corrosion, shock and abrasion. It is estimated that more than 75 per cent of PVC conduits will have a lifetime of more than 40 years with potential in-service lives of up to 100 years.
  • Cost-Effective:- PVC conduits are cost-effective due to its durability compared to traditional alternatives.
  • Environmentally Sound:- In lifecycle analysis and independent studies, PVC conduit's environmental impact has been found to be favourable when compared with other manufactured materials used for wiring.
  • Good Insulator :- PVC conduits do not conduct electricity and are therefore excellent for electrical wiring.
  • Recyclable :- PVC conduits can be recycled at the end of their useful lives.
  • Superior Technical Qualities :- PVC conduits possess excellent technical qualities. They are competitive in terms of cost, are easy to install and require only low maintenance. The extrusion process plus the fact that PVC is light in weight, allow long sections of pipe to be made, minimizing the number of joints. This reduces the cost of assembly. They are also less likely to burst in freezing weather than traditional alternatives. PVC conduits have the advantages of being poor conductors of heat or sound.

konseal PVC Conduits are perfect for electrical applications, because of PVC's resistance to breakdown under high electrical voltage. It is also a poor conductor of electricity. konseal range of conduits are resistant to weathering, chemical rotting, corrosion, shock and abrasion. Manufactured on fully automated machines, konseal PVC Conduits are made of impact modifying, insulating compounds, mixed at 140° C in high speed mixers. With stringent quality control measures in place, it is no wonder that the product meets BIS Standards and is ISI certified

Conduit Installation - Methods Surface Installtion

In surface installation, the conduit is fixed using saddles or spacer bar saddles. The maximum recommended spacing between the saddles is 1.0 m for the horizontal conduit runs and 1.25 m for vertical conduit runs. Saddles should be fixed 20 cm on either side of bends or boxes. As PVC conduit expands, with increasing temperatures, for expansion/contraction movements in long straight runs, the use of an expansion coupling is recommended every 6 m to absorb expansion and avoid conduit buckling.

Conduit Cable Capacities
Single-Core PVC

Insulated cables in straight runs of conduit not execeeding 3m in length

For each cable, it is intended to use, obtain the appropriate factor from Table A. Add all the cable factors so obtained and compare with the conduit factors given in Table B. The conduit size, which will satisfactorily accommodate the cables, is that size having a factor equal to or exceeding the sum of the cable factors.

Single-Core PVC

Insulated cables in straight runs of conduit execeeding 3m length or in runs of any length incorporating bends or sets

For each cable, it is intended to use, obtain the appropriate factor from Table C. Add all the cable factors so obtained and compare with the conduit factors given in Table D, taking into account the length of run it is intended to use and the number of bends and sets in that run. The conduit size, which will satisfactorily accommodate the cables, is that size having a factor equal to or exceeding the sum of the cable factors.

 

Bending

 

Bending of conduit up to 25 mm diameter can be carried out cold, using the correct bending spring size, according to the diameter and the gauge of the conduit. After inserting, the bend can be made by hand or across the knee, by bending slightly beyond the required angle, and allow the conduit to recover back to the required position. The bending should not be done too fast and once made a bend should not be forced backwards, as this action can lead to conduit or spring damage. According to IEE regulations, the bend inner radius should not be less than 2.5 times the conduit's outside diameter.

For conduit sizes over 25 mm diameter, hot bending is required with the same procedure as cold bending, but with the application of gentle heat just before bending. No open flame should be used for heating, rather a hot air torch or hot water. Once the conduit is warm, it can be bent around a suitable former and held there until it cools down and sets in position.
