Image note: Existing photographs are submitted project references. The added lattice-tower image is a representative application reference and is not presented as KOVYEL construction work.
How comparable 110kV mountainous-line packages can be coordinated around ACSR 240/40, OPGW and lattice towers.
This public reference verifies the route basis, lattice towers, ACSR 240/40 conductor and OPGW. The matching logic below explains how KOVYEL would support a comparable 110kV equipment package without implying supply items or quantities that are not publicly verified for this project.
ACSR 240/40 conductor hardware
Suspension clamps, tension assemblies, repair and connection fittings are selected from confirmed ACSR 240/40 construction data, span conditions and approved drawings.
OPGW, vibration and grounding coordination
OPGW suspension and tension fittings, vibration dampers, downlead accessories and grounding fittings are matched to cable data and the mountainous route environment.
A traceable path from BOQ review to export handover.
The workflow below is the standard control path for a comparable equipment or material package. Final deliverables follow the confirmed order scope, approved drawings and agreed inspection plan.
- 01
Confirm system basis
Record voltage, frequency, standards, service environment and customer-approved technical inputs.
- 02
Normalize the BOQ
Align item codes, descriptions and quantities; flag missing data, overlaps and unclear scope boundaries.
- 03
Match drawings and interfaces
Check conductor, insulator, pole or tower, attachment, cable and grounding interfaces against revision-controlled drawings.
- 04
Prepare the technical package
Organize datasheets, general arrangements, drawings, schedules and a clear deviation or clarification record.
- 05
Coordinate quality documents
Define the applicable inspection plan, material certificates, dimensional records and release documents for the confirmed order.
- 06
Pack and hand over
Use BOQ-linked package identification, shipping marks and a document index to support receiving and export delivery.
Evidence purchasing and engineering teams can review.
The document set is defined by the confirmed product scope and agreed inspection plan. Typical controls for a comparable package are summarized below.
Drawing and revision control
Approved drawings, interface schedules and revision status are kept aligned with BOQ item references.
Material and inspection records
Applicable material certificates, dimensional checks and inspection records are indexed by product family.
BOQ-coded packing control
Package marks and packing lists connect cartons, bundles or cases to BOQ lines for easier receiving checks.
Technical document handover
Datasheets, drawings, inspection records and the final document index are organized for engineering and purchasing review.
