Mounting - GE Kelman TRANSFIX 1.6 Installation Manual

7 MOUNTING

Depending on requirements and the installation environment, the product can be
mounted on a separate standalone mounting stand (recommended) or direct mounted to
the body of a transformer. When considering where and how to mount the product,
observe the following points to ensure an appropriate mounting configuration:
The location for the product shall allow easy access to the transformer oil
supply and return valves, so that tubing runs can be kept to a minimum,
particularly in case of extreme temperature. The supply and return tubing runs
between each transformer valve and the product connection point should not
exceed 30 m (98 ft) in length, or 60 m (196 ft) in total length for the complete oil
circuit.
Note: This avoids putting stress on the internal pump and also reduces the possibility
of oil cavitation.
If the recommended GE mounting stand is not purchased, a structurally sound
weather-resistant mounting that supports the 80 kg (177 lb) of the TRANSFIX
1.6 / MULTITRANS, or the 90 kg (199 lb) of the TAPTRANS must be available (see
Appendix G for dimensions). It must also be designed to be securely fastened to
a flat mounting surface. Additional reinforcement and/or dampening may be
necessary if local conditions (environmental or otherwise) could expose the
product to potential external forces or vibration.
The product must be mounted on a flat surface within 5 degrees of plumb and
level on both axes, which is capable of supporting the combined weight of the
product and its mounting stand. (See Appendix G and Appendix H.)
If a new concrete pad is required, GE recommends that it be at least 61 cm (24
in.) wide by 122 cm (48 in.) long and 9 cm (3 ½ in.) thick with a #3 (10 mm) steel
reinforcing bar around the perimeter. (Earth bonded as per local or site practice
and code.)
The product must not be mounted where it could interfere with the regular
maintenance of the transformer.
The product must not be mounted where it could interfere with the airflow of
the transformer's cooling system.
At least 100 cm (3.3 ft) must be kept clear of the Peltier cooler. The airflow to the
vent areas on the bottom and sides of the product must not be blocked or
restricted in any way. See Appendix Figure F—1.
At least 75 cm (2.5 ft) must be kept clear directly in front of the product. The
front door of the product opens for access during installation, maintenance and
operation.
It is acceptable to mount the product to the body of a transformer, which is
exhibiting normal operational levels of vibration, provided that
