5.1.3 Cable install

Connetics has specialist plant and expertise to move a wide range of cable types, from high-capacity power cables to light-weight telecommunications cables. Methods range from winching, using load limiting devices, to blowing and suction methods for fibre cables. 

Air Excavation System

Developed for non-destructive excavation the air excavation system is well suited to larger excavations around multiple services.  The non-invasive system ensures minimal disruption to the root systems of trees and shrubs. 

Utility Locating

This non-intrusive approach is used primarily for the location of under ground power cables and is highly effective in detecting below ground services such as drainage, water and gas pipes, and telecommunication cables.

The Connetics Utility Locating team has over twenty years combined experience and uses the principle of electromagnetic surveying to aid in the location and mapping of underground utilities.

Cable Joint and Termination

Connetics is well versed in the development of innovative jointing techniques that extend beyond standard XLPE and paper insulated lead, aluminium and plastic-sheathed distribution cables to high-voltage flexible rubber mining cables, oil-filled cables up to 66kV and telecommunication cables.
