UNPLASTICIZED POLYVINYLCHLORIDE ELECTRICAL INSULATING TUBES
Rigid PVC electrical tubes are recommended for the protection of instalations up to 1000 V.
Appearance :
The tubes are straight, with circular cross section and ends cut perpendicularly to the axis; the outer and inner surface of the tubes are smooth, free of cracks, porosity or inclusion of impurities; slight waves are admitted.
Colour :
Natural or coloured
Sizes :
Length 3 +/- 0,03 m
Packing of tubes :
The tubes are delivered in bundles tied with a resistant thread, in three places.
The storage and transport of tubes
:
The tubes are stored in covered
spaces or far away of direct UV action.
The storage temperature is recommended to be from +50C up to +400C. The tubes stored below +50C must be kept min. 24 hours at temperature of +150C .. +250C
before being used.
The tubes are kept in horizontal gunracks, stowed at a max. height of 0,75 m.
The transport of tubes is done in covered means of transport, taking into
account all above recommandations, concerning their arrangement.
