Bangor Hospital

Bangor Hospital serves the North West area of Wales and is the biggest hospital in the area with A&E, surgical and maternity wards including other specialist units. The North West Wales Trust felt that the existing electrical infrastructure posed a risk to continuity of supply due to the age, capacity rating and current HV asset arrangement.

Key Benefits

Installation of new HV cabling to ten new power transformers
Provision of SAP for preparation of schedule for switching operations
Interconnections to DNO substation including terminations

Background

The Project

Quartzelec won the contract for the HV cable installation which involved around 2Km of HV cabling; this involved working closely with the Main Contractor for the routing of the ladder racking and access points for cable pulls.

Liaison between our subcontractors and the Main Contractor was essential to ensure that the cable installation and provision of access went smoothly.

Once all of the cables had been installed and pressure tested, the Quartzelec HV Construction team then terminated the cables onto the power transformers in the remote pods and at the ABB HV switchboard ends. All main switchboard interconnections were also completed.

After all of the HV terminations had been done and witness tested by the Trust, Quartzelec were asked to make provision for a Senior Authorised Person on-site on a full-time basis while the HV switchboards were commissioned.

The existing feeders from Scottish Power have now been diverted onto the new G59 switchboard. During the course of the works, Quartzelec were also asked to install a Fibre optic cable between each of the pods.
