Transmission Lines & Distribution: What You Should Know
An overview of how MV lines, substations, and LV distribution work — and how Xi-TEK handles it all.

Electrical transmission and distribution is the backbone of how power gets from a generation source to your home or business. Xi-TEK works on both MV overhead lines and LV distribution infrastructure — here's a plain-language overview of what that involves.
Transmission vs Distribution: What's the Difference?
Transmission lines carry electricity at high voltage (typically 33kV and above) over long distances from power stations to substations. Distribution networks then step that voltage down (to 11kV or 400V) and deliver it to end users. Xi-TEK works primarily on the MV (medium voltage, 11–33kV) and LV (low voltage, 400V and below) segments.
Xi-TEK works on: MV overhead line erection & stringing, substation commissioning (33/11kV), LV distribution board installation, and rural electrification projects.
MV Overhead Line Work
This includes pole erection, conductor stringing, insulator fitting, and terminations. Our team is trained and equipped for medium-voltage outdoor line construction — including ADSS fibre attachment where required.
LV Distribution Boards
Distribution boards (DBs) are the panels that split incoming supply to individual circuits. We design, build, and install LV DBs for residential compounds, commercial buildings, and industrial facilities — with proper protection devices, load balancing, and metering.
Substation Work
- 01. Transformer installation and termination
- 02. Panel wiring and busbar assembly
- 03. Protection relay setting and testing
- 04. Earthing and bonding
- 05. Commissioning and energisation support
