SOHAN LAL & SONS (POLES) PVT. LTD.

TUBULAR POLES

MANUFACTURING PROCESS:

Swaged poles shall be manufactured from E.R.W./Weld Tubes of suitable lengths swaged & joined together. No circumferential joints shall be permitted in the individual tube lengths of poles. The longitudinal welds shall be staggered at each swaged joint. Swaging is done by Hydraulic Power Pack Unit. A circumferential weild shall be deposited at the upper end of the joint at a slope of approximately 45·.Poles manufactured by us normally conform to IS 2713(Part-II)-1980 and special sizes poles can also be manufactured by us as per customer drawings or requirements.

EARTHING ARRANGEMENT:

If earthing arrangement is required, a bolt of 10 mm dia is welded on each pole at a height of 300 mm above the planting depth, or can be provided as per customer’s requirements.

ADVANTAGE:

Steel Tubular poles are the most efficient and economical source for carrying the overhead transmission and overhead distribution lies which no other source can take place. Owing to the circular cross section, the poles will stand torsional stresses much better. Cylindrical surface offers minimum wind resistance and due to their elasticity, can take all sorts of shocks, cyclones, thrust line breakage etc. far better than any other type of poles. Being light weight permits easy handling, transportation, low depth erection and less maintenance cost which ensures the greatest economy of steel tubular poles.
