Equipment Hire

 

It is impossible to predict issues arising with your electrical power system. Sometimes unanticipated events such as emergency outages, equipment failure or utility network upgrades occur. Although you can’t always anticipate these events, Slaters equipment hire can offer you a temporary power solution should these unplanned or indeed planned situations arise.

Why Choose Equipment Hire?

Our fleet of industrial power equipment is available for hire, and is a timely, cost effective and flexible answer to your temporary power requirement. Equipment hire solutions can be available immediately, integrated into your existing site set up and there is no large upfront investment needed.

  • Have you had an unexpected transformer failure?
  • Do you have generators, maybe several in parallel, which you need supply a high voltage distribution system?
  • Do you need temporary equipment to cover the lead time on new equipment?
  • Do you need a non UK standard voltage eg for testing electrical equipment for export?
  • Do you need a 690V supply for a variable speed drive?
  • Have you had a distribution switchboard, or vacuum contactor motor starter failure?
  • Do you need site supply and distribution during construction work?
  • Do you need alternative distribution during a factory maintenance shut down?
  • Do you need a high voltage circuit breaker truck whilst yours is repaired?

These, and others, are all common situations where equipment hire, including transformers and switchgear, has been the right solution in recent years.

High Voltage Transformers

  • All items in our secondhand stock from 40MVA down to 50kVA are available for hire
  • New transformers are available for longer hires, if required

We have transformers of different sizes covering 132kV, 66kV, 33kV, 20kV, 11kV, 6.6kV, 3.3kV 1.1kV mainly step down to 415V, some step up or step down from 11kV, others step up from 6.6kV, 3.3kV, 415V or 400V.
We also stock a few unusual voltages including 7100V, 5600V, 4160V, 690V, or 340V (for Solar PVs).
Also 1:1 ratio 11kV 4 & 3.5MVA.

If required we can fit most transformers with a high voltage isolator, circuit breaker or ring main unit.

Container Mounted Substations

In addition, we have 2 container mounted transformer substations, purpose built to give various high voltage output from parallel multi-generator input.

Both substations:

  • contain a 6300kVA multitapped high voltage transformer suitable for step up from star connected 400V 50hz or 480V 60hz inputs
  • consist of 2 x 3150kVA double wound oil cooled transformers, arranged for individual or parallel operation
  • are mounted in a 20ft ISO container, with end and side access doors and cable access points

Substation A

Rated 50hz HV outputs, star connected : 22, 20, 18, 15, 11, 10, 9 kV
Rated 50hz HV outputs, delta connected : 12.7, 11.5, 10.4, 6.3, 5.8, 5.2 kV

Rated 60hz HV outputs, star connected : 26.4, 24, 21.6, 13.2, 12, 10.8 kV
Rated 60hz HV outputs, delta connected : 15.2, 13.8, 12.5, 7.6, 6.9, 6.2 kV

Transformers are fully rated across the range except for the 15kV 50hz output which is 2 X 2500kVA
Transformers are fitted with cooling fans and each will uprate to 3750kVA with ONAF cooling

The high voltage output is distributed through a 4 panel switchboard comprising 2-630A 24kV rated isolators and 2- 630A 24kV rated vacuum circuit breakers cabled from the transformers.. Low voltage feed is through 6- 2500A 4 pole Isolators for supply from parallel generators.

Substation B

Rated 50hz HV outputs, star connected : 12.5, 11.4, 10.3, 6.3, 5.7, 5.13 kV
Rated 50hz HV outputs, delta connected : 7.2, 6.6, 5.9, 3.6, 3.3, 3.0 kV

Rated 60hz HV outputs, star connected : 15, 13.7, 12.3, 7.5, 6.8 , 6.2 kV
Rated 60hz HV outputs, delta connected : 8.7, 7.9, 7.1 , 4.3, 4.0, 3.6 kV

Transformers are fitted with cooling fans and each will uprate to 3750kVA with ONAF cooling

The high voltage output is distributed through a 4 panel switchboard comprising 2 outgoing 630A 24kV rated isolators and 2-630A 24kV rated vacuum circuit breakers cabled from the transformers. Low voltage feed is through 6- 2500A 4 pole isolators for supply from parallel generators.

Medium Voltage Transformers

We hire transformers covering the following voltages:

  • 415V, 565V, 1100V – transformers available: 500 & 650kVA
  • 415V, 600V, 660V, 690V – transformers available: 50, 100, 150, 250, 500 & 1500kVA
  • 415V, 550V – transformers available: 150 & 450kVA
  • 415V, 380V – transformers available: 30kVA to 150kVA
  • 415V, 210V – transformers available: 50kVA to 250kVA
  • 1:1 ratio double wound isolating transformers available 50, 75, 100 & 240kVA
  • We have several multi tapped transformers upto 240kVA with output ranges 550-220V

The voltage output from a generator may be adjustable thereby extending the output range of an accompanying transformer, if required.

Switchgear – Medium & High Voltage

We hire single item or multi-panel switchboards, ground or transformer mounted, or built into ISO containers as required, from our extensive stock of used equipment.

Switchgear is available for short or long term hire and our highly experienced, specialist teams can deliver on-site installation if required.
