OVERVIEW

IUS were contracted to construct a new 1000kVA, 11000/433V UDE substation comprising a transformer with close coupled 11kV ring main unit and 1600amp ACB to provide a bulk LV supply to the site metered at LV.

DESCRIPTION

IUS undertook the design, procurement, installation, and commissioning of the Northern Powergrid (NPg) contestable works, which comprised the 11kV Ring Main Unit and the associated 2 No. 11kV, 300mm triplex cables. These cables were installed on private and public land to the NPg point of connection. This element also included the design and installation of the earth nest for the whole substation to NPg specifications.

IUS also undertook the design, procurement, installation, and commissioning of the IDNO (ESP) element of the project which comprised the transformer with close coupled ACB. IUS also advised the client with regard to the overall construction of the substation and the standards required by both the DNO and the IDNO in order for the adoption by both parties to be achieved.

The substation was tested, commissioned, and energised with the appropriate apparatus adopted by NPg and ESP.

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.

  • 11kV Contestable connection work
  • On site private 11kV infrastructure work
  • Procurement of equipment
  • Installation of DNO and private 11kV switchgear
  • Installation of 11kV cables
  • Modifications of the existing 11kV ring
  • Heavy lifting operations
  • Testing and commissioning
  • Preparation of handback documentation
OVERVIEW

IUS completed the electrical construction works associated with Unilever’s supply upgrade at their site in Leeds. In order to provide a 4.3MVA supply, a new 11kV Distribution Network Operator (DNO) substation was required, as well as new private 11kV switchgear and transformers. IUS were appointed to undertake the design and installation of the 11kV contestable elements of the connection works along with the private 11kV and LV infrastructure.

DESCRIPTION

The project involved extending the DNO’s local 11kV network c. 220m to a point on Unilever’s site and supplying and installing a new 11kV intake substation complete with an 11kV metered ring main unit.

Modifications to the existing 11kV private network were required to facilitate the connection upgrade as well as the supply and installation of an 11kV switchboard, local 11kV ring main units, 11,000/433V transformers and a low voltage switchboard. Due to the nature of the site, IUS were required to work to a tight programme. The contract was delivered to the agreed timescales.
