66kV Cables

Gas Filled High Voltage Cable Jointing

The 66kV 3 core high pressure (200 psi) gas joint (nitrogen) was made for SSE by Matthew Taffs of CRS Ltd and John Beck both working for Balfour Beatty at the time.

The 66kV cable construction was oval copper conductor with a lead sheath and steel reinforcing tapes with hessian wrapped layer. The manufacturer of the cable joint was Glovers (W T Glover) of Trafford Park, Manchester which later became part of BICC.

The cable joint is from the 1950’s and when the joint was unpacked from the wooden create it was still packed in straw. The insulation of the cable had to be stepped down to the conductor known as pencilling using piano wire and weights.

The joint consisted of a two piece split ferrules which was sweated on the conductor with tinmans metal. Once sweated the ferrule was cleaned up and the insulation was ready to be applied. The insulation was flat/plain paper tapes (not crepe) coated in a thin layer of grease and was applied with care by the jointer. Once built up to the final diameter the end profiles had to be skilfully teared down using piano wire and weights again. The metallic screen reinstated from one side to the other and then each core is covered in terylene tape.

Both end cable glands of the joint had internal plumbs /wipes and when the plumbing was finished – hot oil was poured on followed by a hot metal into the cable gland to reinforce the steel tapes and lead sheath as this 66kV cabling system is such high pressure it would split the lead sheath.

Once the 66kV joint was finished the jointer bolted the sleeve to the cable gland and turn on the nitrogen gas and check for leaks. The 66kV joint could be protected in either a Glo (Glovers) Sleeve filled with compound/ bitumen or heat shrink. The job was project managed by Gary Horne, now of CRS (Cable Repair Services) Ltd.

66kV Polymeric Cables

21st century cable manufacturing is dominated by polymeric type insulated cables and for offshore wind farm power generation including subsea power, array, inter-array and intra-array cables – to support this type of 66kV high voltage cable infrastructure Thorne & Derrick via their distribution agreement with Nexans can supply a complete range of joints, terminations, connectors and surge arresters detailed below.

66kV Cables – Offshore Wind Farms

Company History – Walter T. Glover & Co

Walter T. Glover & Co of Trafford Park, Manchester and London, were electrical cable manufacturers.

1868 – Company founded with premises at the Bridgewater Street Iron Works in Salford. The founder, Walter T. Glover, was a commercial machinery agent for the Lancashire cotton industry.

1959 – BICC acquired 50% of Submarine Cables Ltd which was used to manufacture and install power cables. Glover’s submarine cables were used to link England and France, and the north and south islands of New Zealand. However, although the company appeared to be doing well, there was increasing international competition to supply cables. The south side of the Trafford Parks works was integrated into the newly formed Wiring and General Cables Division of British Insulated Cables (BICC).

C&P Awarded Contract for 30MW STOR Gas Generation Facility

C&P Awarded Contract for 30MW STOR Gas Generation Facility

Press Release By Tristan Jones (Sales & Marketing Manager - C&P Engineering Services Ltd)

C&P Engineering Services are delighted to announce that is has been awarded the design and build contract by Enersyst Limited (part of the Walters Group of Companies) for a STOR (Short Term Operating Reserve) 30MW Gas Generation Facility, located off Smoke Lane in Avonmouth, Bristol.

Short Term Operating Reserve

The 30MW STOR facility is one of a number of projects created to service National Grid balancing services. STOR is a demand-side service used by National Grid to provide additional active power from generation or demand reduction. The contract will include full civil and electrical design and build balance of plant works and will include designing, engineering, supplying, installing, constructing, testing and commissioning a fully furnished and operational 30MW gas STOR generation facility.

The project will finally consist of fifteen containerised gas powered gensets, together with associated infrastructure, including vehicle access, pedestrian walkways, foundations, site electrical works, SCADA, substation, control room, transformer and other ancillary items.

The site was first developed in the mid-1960s by Butler Chemicals and was subsequently occupied by Albright and Wilson (1967), Tennaco (1984) and Rhodia (2000). Albermarle Chemicals UK Ltd purchased the site from Rhodia in 2003. The majority of the demolition completed by early 2013.

Over the next 12 months C&P will be working on the design, electrical infrastructure, scada system, cable system, switchgear, M&E fit out of the control building, auxiliary supply to the control building, grid compliance, design of capacitor bank, design and installation of earthing network, testing, commissioning and energisation of the 33kV private network.

David Demock, HV Engineering Manager commented: “This is C&P’s first project with Enersyst and we’re excited to deliver the full balance of plant elements of this 30MW site and a fully operational gas STOR generation facility”.
