IUS delivered this work under our as an accredited Independent Connections Provider (ICP). 

Client

Tosoh Quartz

Project

Increased HV Supply Capacity to Factory

Location

Greencroft, County Durham

SERVICES PROVIDED
  • HV and LV design
  • ICP 20kV connection comprising:
  • GRP substation accommodation
  • 20kV metered ring main unit
  • 500kV transformer with close coupled
    LV board HV and LV cabling
  • Customer replacement LV switchboard
  • Construction to the adoptable
    standards of NPg
OVERVIEW

IUS delivered this work under our as an accredited Independent Connections Provider (ICP). Therefore, the works were carried out to the adoptable standards of the Distribution Network Operator, Northern Powergrid (NPg). The scope included the design, procurement, and installation of a 20kV distribution substation, low voltage sub-mains cabling, and a replacement customer low voltage switchboard to provide an increased supply capacity to the Tosoh Quartz factory in Greencroft, County Durham. The facility produces quartz glassware for the semiconductor industry for use in the processing of integrated circuits.

DESCRIPTION

IUS project managed the installation of the substation building to specification. The 115- meter feeder route encompassed 2 x 185mm aluminium 20kV XLPE Triplex cables to the point of connection onto the NPg network. Cable trenches were excavated on both private land and the public highway. IUS HV electrical fitters completed the installation of a 20kV
ABB safe plus ring main unit, 500kVA transformer with close coupled LV cabinet, earthing, protection, and metering cabling. IUS HV Jointers carried out the HV cable terminations. An IUS protection engineer conducted the pre-commissioning and witness testing for NPg. The IUS Senior Authorised Person provided the necessary safety documentation and oversight of the works. Customer LV sub mains cables were installed from the substation into the factory on high-level containment to supply a new low-voltage switchboard. Existing factory supplies were reconnected to the new switchboard during a planned outage giving the customer scope for their future expansion plans.

New Wren Kitchens Manufacturing Factory 15MVA Connection and 11kV Infrastructure

Location

Barton-upon-Humber

SERVICES PROVIDED
  • Project management and site supervision
  • Health and safety documentation
  • Senior authorised person provision
  • Earthing study and design
  • Protection and grading study
  • Supply and installation of 11kV switchgear
  • Supply, installation, and commissioning of transformers with close coupled 11kV ring main units
  • Supply and Installation of all 11kV cable
  • Supply and installation of all 11kV earthing
  • Provision of operation and maintenance manual on completion of the project
OVERVIEW

The scope of works was to design, supply and install a 15MVA, 11kV network including substations and interconnecting cables to provide the power for a new Wren Kitchens Factory constructed adjacent to the existing Wren Kitchens site in Barton-upon-Humber.

DESCRIPTION

IUS completed the design of the 11kV system earth installation, including ground surveys and testing to ascertain the ground resistivity around site to be used in the earthing model. All earthing apparatus was installed to the design resulting in compliant earth nest readings.

A protection and grading study was undertaken of the 11kV network from the Northern Powergrid (NPg) metering breakers, through the customers intake 11kV switchboard and transformer, including the largest LV ACB’s, to ensure correct protection and grading for the new 11kV system.

Following design, a new client owned 11kV intake substation, comprising a 7 No. panel extensible switchboard, was supplied and installed at the perimeter of the site. Also installed were 2 No. 11kV 300mm Copper Triplex cable loops between the clients’ switchboard and the NPg switchgear in the adjacent rooms. This also included liaison with NPg on the final connections and operational requirements to ensure a seamless “power on”.

The scope of services also included the supply, installation and commissioning of 12 No. 1500kVA, 11000/433V transformers and 2 No. 1000kVA transformers, all with close coupled 11kV ring main units, installed within 4 No. substations around the site.

To create 2 x 11kV rings, IUS supplied and installed 4.5Km of 300mm Aluminium 11kV Triplex cable to provide connection between the clients’ new intake substation and the 4 No. aforementioned substations.
