33kV, 35kV and 36kV Overhead Line Equipment Package
A complete 33/35/36kV overhead line material package for long-distance distribution, utility feeders and EPC tenders, coordinated from structures to cable transition.
What is included in a 33kV or 36kV overhead line EPC supply package?
A 33/35/36kV supply package normally combines poles or light towers, AAAC/ACSR conductors, 36kV-class insulators, suspension and tension hardware, joints and dampers, protection and switching equipment, transformer or cable-transition interfaces, earthing, fiber accessories and project-coded shipment documents. The project must confirm whether 36kV or 40.5kV equipment is required.
TYPICAL SYSTEM BASIS
33/35/36kV starting point.
The following values organize the first technical review. They do not replace the utility specification.
Nominal system
33kV, 35kV or 36kV
Equipment class
36kV or 40.5kV
Frequency
50Hz or 60Hz
Structures
Poles or light lattice structures

TECHNICAL COORDINATION
Interfaces to close before final quotation.
01
Confirm the highest equipment voltage before selecting arresters, switches, insulators and cable accessories.
02
Use the pole schedule to separate tangent, angle, dead-end, terminal and transformer structures.
03
Coordinate conductor mechanical data with string hardware, compression tooling and vibration control.
04
Check whether the communication system uses OPGW, ADSS or a separate telecom route.
