Steel Tubular Power Transmission Pole

Product Specification

                                   Steel Tubular Electric Power Transmission Pole Process With Ambush Welding

Product Description

The products above are 220KV Tubular Steel Pole for Transmission Lines,230kv electric pole, EN stardand.
To design in accordance with PLS software, we will require the following design parameters:

1. The operational wind speed of the region where the pole will be used
2. The Antenna load and height of the pole
3. The total height of the pole itself

Product Specifications

3.2. Tolerances

• Mean outside diameters, measured at slip joint level: ±1 % with ±2 mm minimum
• Ovalization: the dimensional percentage noted for two measurements taken between two perpendicular diameters at slip joint level : less than 3 % [(Dmaxi-Dmini)/Dmaxi < 3 %]
• Length of pole elements: - 25 mm / +75 mm
• Members Straightness: less than 0.2 % of 1 meter member length (2 mm per meter)
• Twisting: less than 1.5 degrees per 3 meters member length
• Location of holes: ± 1 % on lengths indicated on our approval drawings

3.3 Galvanization

After the fabrication has been entirely completed, Steel Poles shall be hot dip galvanized. Double dipping shall not be allowed.

All materials, except bolts, screws, nuts, shall be galvanized according to NF EN ISO 1461.

All hollow members shall be galvanized both inside and outside surfaces. Nuts shall be retapped after galvanizing and then shall be suitably protected from rust by grease.

4. Description:

Galvanized STEEL POLES, uniformly tapered, 12 sided regular polygonal cross-section. The maximum length of one section shall be 12 meters.

Each face shall be flat, without stiffeners except at load points.

Steel Poles are designed for telescoping slip-fitted connections.

Poles are designed with a minimum number of joints (one or two joint per pole). Pole joint shall be of telescoping type, welding or bolting shall not be employed.

Slip joint length shall not be less than 1.5 times the major internal diameter of the upper element.

A removable metallic pole cap shall be fitted on top of poles.

The crossarms attached at the same level on opposite sides of the pole shall be symmetrical about the centerline of the pole and shall be such that each crossarm can be installed independently.

The crossarms shall be connected to pole by mean of thru vangs, bolts and nuts. Cross-arms shall be straight and shall have a uniformly tapered 6 (eight) sided regular polygonal cross-section

All poles shall be provided with one earthing point at a position approximately 50 cm above ground level.
 
Packaging & Shipping

We cover the top and bottom parts of the pole with a mat or straw bale in order to protect it from damage to the galvanized surface that may occur during transportation. Packaging can also be done according to clients’ requirements.

Process of Production

Verification of Materials → Cutting → Molding or Bending → Vertical Welding → Verification of Dimensions → Flange Welding → Hole Drilling → Calibration→ Deburring Process → Galvanizing, Powder Coating or Painting → Recalibration → Threading → Packaging
