HEVI-DUTY
General Purpose Transformers
Specification Guide for Low Voltage, General Purpose,
Dry Type Transformers (600 Volt Class) -15 KVA and larger
General
Single and three phase distribution transformers
(600 Volt and below)
• Provide and install, as referenced on the electrical
plans, enclosed dry type transformers as manufactured
by Sola/Hevi-Duty or approved equal.
Standards
• Transformers must be listed by Underwriters
Laboratory, certified with Canadian Standards
Association and designed, constructed and rated in
accordance with NEMA ST 20, ANSI C89.2 and
applicable IEEE & OSHA specifications.
Construction
Cores
• All transformer cores shall be constructed of low loss,
high quality, electrical grade laminate steel. By design,
the flux density is to be kept well below the saturation
level to reduce audible sound level and minimize core
losses. The core volume shall allow operation at 10%
above rated primary voltage at no load without
exceeding the temperature rise of the unit.
Coils
• Coil conductors shall be either aluminum or copper and
must be continuous. The entire core and coil assembly
shall be impregnated with a thermal setting varnish and
cured to reduce hot spots in the coils and seal out
moisture. Coils with exposed magnet wire will not be
acceptable. Transformers shall have common core
construction.
• All transformers shall incorporate a faraday
(electrostatic) shield between primary and secondary
windings for the attenuation of voltage spikes, line
noise and voltage transients.
• Transformers shall be provided with six 2.5% full
capacity taps - two above and four below primary rated
voltage.
Enclosures
• Transformer enclosures shall be constructed of heavy
gauge sheet steel and coated with a grey powder paint
finish (ANSI 6 1 ) . Ventilated transformer enclosures
shall be UL/NEMA Type 2 rated and UL/NEMA Type
3R rated for outdoor use with the addition of a
weathershield. This information must be listed on the
transformer nameplate.
• Maximum transformer enclosure temperature will
not exceed 65°C rise above a 40°C ambient under
full load.
• Transformers must have vibration isolators located
between the core and coil assembly and the
transformer enclosure to reduce audible sound levels
caused from magnetostriction of the transformer core.
No externally located vibration dampening pads shall
be used as they tend to increase audible noise.
Ventilated transformers are to be floor mounted to a
concrete pad.
• The transformer enclosure must be grounded by the
installer in accordance with the latest edition of the
National Electric Code and any local codes or
ordinances.
Performance
• Audible sound levels will not exceed limits established
in NEMA/ANSI Standard C89.2:
10 to 50 KVA
51 to 150 KVA
151 to 300 KVA
301 to 500 KVA
• Transformers, 15 KVA to 500 KVA, shall incorporate a
UL recognized 220°C insulation system and exhibit a
maximum 150°C temperature rise above a maximum
ambient of 40°C under full load.
• General purpose transformers are classified as
isolation transformers.
