RECOMMENDED PRACTICE

ASTRAL   WIRE   GUARDTM non-metallic conduits are socables. The actual number of cables drawn into any conduitconstructed that it will bepossible to bend the conduit easily with the aid of bendingspring and all conduits and conduit fittings are of unthreaded type.The number of single core, PVC insulated non-sheathed cables runin one conduit shall be such that it permits easy drawing of the cables.The actual number of cables drawn into any conduit shall   notbe   greater   thanthe   number   givenin   the appropriate table.  Wheredifferent  sizes  ofcables  are drawn  intoa  conduit,  thenumber  and  sizesof  cables installed shall beselected in accordance with the method detailed in tables. A separate insulatedearth wire shall be drawn into all rigid non-metallic conduits.

For each size of cable it is intended to use, obtain the appropriate factor from Table 4. Add all the cable factors so obtained and compare with the conduit factor given in Table 5.

The conduit size which will satisfactorily accommodate the cables is that size having a factor equal to or exceeding the sum of the cable factor.

HIGH CORROSION RESISTANCE :
 
ASTRAL WIRE GUARD is non-corrosive by nature and are not attacked by corrosive, salty atmosphere & excessive humidity. They are immune to chemical and galvanic corrosion. Hence they are ideal electrical conduits.
 
FIRE RESISTANCE :
ASTRAL WIRE GUARD do not support combustion and when the source of ignition is removed they are self extinguishing.
 
CONDUCTIVITY :
ASTRAL WIRE GUARD is non-conductor TM of electricity. ASTRAL WIRE GUARD conduit prevents electrical shocks. Hence they are most suitable for electrical conduits.
 
LIGHTWEIGHT :
ASTRAL WIRE GUARD have low specific gravity, which implies that it is much lighter than the pipes made from more traditional materials. ASTRAL® Pipes are therefore easier to handle. This result in reduced transportation & installation costs.
 
EASY WIRING :
ASTRAL WIRE GUARD have smooth interior walls which helps in reducing the friction thus helping in easy wiring.
 
EASY INSTALLATION :
ASTRAL WIRE GUARD can be shaped and joined without difficulty. TM ASTRAL WIRE GUARD Pipes are joined by solvent cement, which is simpler, cheaper & easier.
 
STRENGTH :
ASTRAL WIRE GUARD have high mechanical strength that is attested by tests conduced as specified in IS 9537: 3.
Hence they can be used both in open / surface and concealed installation.
 
NO MAINTENANCE :
ASTRAL WIRE GUARD requires no maintenance due to its excellent weather protected properties.
 
DURABILITY :
ASTRAL WIRE GUARD electrical conduit pipes last for a lifetime.
 
VERSATILE AND ELEGANT :
The physical properties of PVC allow designers a high degree of freedom while designing. Superior finished pipes and fittings add a touch of beauty to the buildings .
 
ENVIRONMENTAL IMPACT :
PVC has a lower feedstock energy especially compared to other polymers and common building materials. It is the least energy intensive of all thermoplastics. In life cycle analysis
and independent studies, PVC's environmental impact has been found most favorable, so the more usage of PVC will greatly help to keep our global natural resources intake for longer
period of time. It is not polluting air, water or land during manufacturing or service life and can be recycled after prolonged service life.
