DIRECT PROJECT ANSWER

What equipment is required for an 11kV overhead distribution line project?

A typical 11kV project needs poles and crossarms, phase conductors or ABC, pin/post/strain insulators, suspension and dead-end fittings, connectors, fuse cutouts, surge arresters, switching equipment, distribution transformers, earthing materials and project-coded packing. Final quantities and ratings follow the approved pole schedule, single-line diagram and utility specification.

COORDINATED SUPPLY PACKAGE

Products matched as one line system.

Every group is checked against the same structures, conductors, insulation, equipment interfaces and approved project codes.

01

Structures & phase system

The physical line and its conductor support system.

  • Concrete, steel or approved utility poles
  • Steel or composite crossarms and brackets
  • AAC, AAAC, ACSR or ABC conductors
  • Earth wire, stay wire and guying assemblies
  • Pole bands, bolts, braces and fasteners
02

Insulation & line fittings

Assemblies matched to conductor, structure and load.

  • Pin, line-post and strain insulators
  • Suspension and dead-end assemblies
  • Connectors, joints and repair fittings
  • Armour rods and vibration-control fittings
  • Jumper and terminal connection hardware
03

Protection, transformation & delivery

Pole-mounted equipment and site-ready material control.

  • Fuse cutouts and metal-oxide surge arresters
  • Load-break switches, disconnectors or reclosers
  • 11/0.4kV distribution transformers
  • 12kV cable terminations and joints
  • Earthing materials, labels, packing lists and export documents

BUYER QUESTIONS

Direct answers for 11kV procurement.

Can KOVYEL quote an incomplete 11kV BOQ?

Yes. KOVYEL can normalize item names, separate structure kits and issue a technical clarification list. Final ratings and quantities still require approved project information.

Can bare conductor and ABC equipment be included in one project?

Yes when the approved design uses both systems, but clamps, connectors, insulation and terminations must be separated by conductor construction and size.

Are poles and transformers included?

They can be included in the coordinated supply package when drawings, ratings, quantities and destination requirements are provided.
