Gray Metal Power Pole For 230KV Transmission Monopole Tower 110FT ASTM A 123

230kv Transmission Monopole tower , Metal Power pole , gray, 110ft, ASTM A 123 , grounding wire

Product Description

The products above are steel utility poles made specifically for230kv Transmission Monopole tower , Metal Power pole , gray, 110ft, ASTM A 123 , grounding wire

The present Paper shows possible line pre-design for the project, but any final design of the line for the project shall be carried on by specialized line designer and shall be fully and formally approved by GRIDCo. These specifications are supplementary to the transmission line specifications provided and should be read in conjunction with them.

• Scope

The project involves the construction of two double circuit transmission lines (approximately 7km and 5km respectively on self-supporting double circuit (DC) monopole transmission line towers using 1 x 604mm² AAC HAWTHORN conductors with the monopole towers fitted with two optic fibre ground wire (OPGW) shieldwires.

Bidders are encouraged to submit alternate specifications/drawings for self-supporting double circuit monopoles and shall price them accordingly for evaluation as alternates.

C) Specification of steel monopoles:

1. Design conditions:

Loading trees showing, for each load case, vertical, transversal and longitudinal loads applied to monopole shall be shall be as described in the technical specifications.

Material partial safety factor γM are applied for calculation of cross-sections on yield stress of steel according to EN50341-1.

Poles analysis shall include second order (or P – Λ ) analysis and checking of local buckling according to ASCE report N° 72. Calculation Note shall be issued and submitted to GRIDCo for approval.

Poles are calculated with a limitation of deflection equal to 8 % of height under factored loads (cf EN 50341 §7.4.5.1.3).

2. Materials:

All materials shall be new and in accordance with relevant standards referred to within this specification.

To design in accordance with PLS software, we will require the following design parameters:

Product Specifications

• Products are designed and manufactured according to ANSI/TIA-222-G structural standards
• Pole shaft material : ASTM GR65,GR50,Q460 A572,S355,Q345/Q235,etc
• We possess the ISO 10046 certification and are committed to giving our customers the best products and service
• We provide additional assistance if required including supervision and supplementary components

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.
