Whether you are considering the installation of new electrical
systems, or simply upgrading an existing application, G. T. Wood
engineers will design each of the above services to meet your
specific requirements.
Equipment Supply & Rental
- Portable high voltage substations
- Power transformers (oil and dry)
- Distribution transformers (pole and pad mounted)
- High voltage switchgear
- Oil circuit breakers
- Tower structures
- Low voltage air circuit breakers
- High voltage breakers
- Moulded case breakers
- Fuses, fuse holders, fuse refills, cable, cable connectors,
flexible braid, flexible braided connectors, insulators,
lightning arrestors and high and low voltage bushings
In the event of an emergency of a planned situation, two mobile
high voltage substations are available to rent. These units can
be modified for transformation at 44, 27.6, 13.8 KV. The size of
the transformers and the low voltage board can also be modified
to suit the requirements of your specific situation.
Flex Connectors
Types of Braid Used:
- Tinned copper tubular
- Tinned copper flat
- Large flat tinned copper
- Multiple layered tinned copper
- 'Shieldnit', knitted wire shielding for cable splicing
Standard Thickness:
600, 900 and 1200A - 1/4' 6.4 mm); 1600 and 2000 A - 3/8' (9.5mm)
Non-Standard Extras
- Current Rating; End contact size; End contact drilling
pattern; Hole size; Thickness; Insulation; Plating.
G. T. Wood flex connectors reflect standard ratings, however,
non-standard sizes can also be produced. Please provide a sketch
to G. T. Wood for quotation.
Electrical Equipment Retrofit
Retrofit programs can be established for various reasons, such
as:
Aging equipment; Equipment failure; Damaged equipment; Relocation
of equipment; System voltage change; System design modification;
Electrical code requirements
Our Engineering department will review the requirements and make
the necessary recommendations.
Our Operations department will provide the technical expertise to
effect the required retrofit program using factory replacement
components.
The following outlines the types of equipment addressed by a
retrofit program:
Interlock systems; High voltage switchgear; Analogue relays;
Mechanical tripping devices on circuit breakers; Ground fault
protection; Power capacitors; Lightning arrestors
A Sales Representative is available to review your system
requirements upon request.
Transformer Repair & Testing
In-House Testing Capabilities
Insulation resistance; DC resistance; Power factor; Dissipation
power factor; Induced high voltage; Core loss; Copper loss;
Ratio; Hi Pot.
In-Shop Repair Capabilities:
- Complete rebuild (using outside source for rewound core and
coils)
- Radiator repair or replacement
- Component replacement on all types of units
- Cosmetic enhancement of damaged units
- Oil supply and installation.
G. T. Wood technicians can also carry out the above repairs
on-site, if necessary and feasible. When required, transformers
can be tested in accordance with CSA standards.
Preventative Maintenance
- Inservice inspections
- Infrared thermographic inspections
- Primary structure and switch maintenance
- Transformer maintenance and testing (all types)
- Transformer insulating liquid evaluation
(Standard 5 part ASTM, Dissolved gas analysis, furan,
Inhibitor, Power factor, PPM/Water, PPM/PCB).
- Air circuit breaker service, testing and calibration
- Protective relay testing and calibration
- High voltage cable location and testing
- Power factor testing / Capacitor inspection
- Complete cleaning & torquing of all electrical connections and
components
- Verification of fuse sizes and condition
- Verification of existing single line diagrams
- Motor control centre inspection
After each maintenance inspection, a complete report will be
issued to you outlining the equipment serviced, any defects found
and any recommendations made for repairs. A copy of the report
will be retained by G.T. Wood as part of your client file.
Regularly scheduled high-voltage preventative maintenance
programs not only reduce operational costs - they're also vital
in reducing the risk of unexpected electrical system failures.
