Product Specifications

At Skipper Limited, we offer our customers a full-range-cum-diverse product basket ranging from 66 KV to 800 KV Towers (Single Circuit, Double Circuit, Multi-Circuit Towers suitable for Twin, Triple, Quad or Hex Conductor configurations). We can offer Tower materials as per Indian as well as International material grades ranging from BSEN to ASTM to GOST.

Tower description

Transmission tower is a tall structure, usually a steel lattice tower, use to support an overhead power line. We render these products with the help of

diligent workforce having vast experience in this field. We go through detailed line survey, route maps, spotting of towers, chart structure and technique document while providing these products.

Our product covers the 11kV to 500kV while include different tower type for example suspension tower, strain tower, angle tower, end tower etc.

Additionally, we still have a vast designed tower type and design service to be offered while if clients have no drawings.

Fabrication Technologies

All tower parts go through multi-purpose hydraulic machine that can carry out various operations such as shearing, punching and cutting. Hydraulic presses along with matching tools, jigs and fixtures ensure that bent items are handled without distortion. Strategically positioned cranes simplify material handling without any strain on employees. All machines are equipped to process steel conforming to various specifications e.g. ISO, ASTM, JIS, DIN.

TESTS

X.Y. Tower has a very strict test protocol to ensure all products we fabricate is quality. The following process is applied in our production flow.

Sections and Plates

1. Chemical composition (Ladle Analysis)

2. Tensile Tests

3. Bend Tests

Nuts and Bolts

1. Proof Load test

2. Ultimate Tensile Strength test

3. Ultimate tensile strength test under eccentric load

4. Cold bend test

5. Hardness test

6. Galvanizing test

All the test data are recorded and will be reported to the management. If any flaws are found, the product will be repaired or scraped directly.

Free prototype tower assembly service

prototype tower assembly is a very traditional but effective way to inspect whether the detail drawing is correct.  

In some cases, clients still want to do prototype tower assembly to ensure the detail drawing and fabrication is OK. Hence, we still provide prototype tower assembly service for free to customers.

In prototype tower assembly service, X.Y. Tower makes commitment:

• For each member, the length, position of holes and interface with other members will be checked accurately for proper fitness;

• Quantity of each member and bolts will be carefully checked from the bill of materials when assembling the prototype;

• Drawings and bill of materials, sizes of bolts, fillers etc. will be revised if any mistake is found.
