General Instructions

2.2.2. Selecting the route for road transport
The route chosen for road haulage must be the one with
the best conditions for transporting heavy loads which are
sensitive to damage from impacts, bangs, vibrations and
accelerations.
Routes that reduce the eff ects of accelerations, vibrations,
impacts and bangs caused by winding roads, changes of
gradient and the cant of the road should take precedence
over shortest distance.
As far as possible, priority should be given to the highest
category of motorways with minimum slope, maximum
linearity and best road surface condition.
mb
.m is prepared for transport on fl at, paved roads without
signifi cant potholes.
On uneven road sections, transport speed should be
reduced in order to ensure the load does not suff er sudden
acceleration and deceleration.
Traffi c and transport rules in the corresponding
country must be respected in all cases.
If transport for the
mb
.m is to include untarred road
surfaces, the customer must indicate this circumstance
in the order sent to
Ormazabal
. Following this
communication, the best solution for transport will be
decided between the customer and
Ormazabal
.
2.2.3. Checking impact detectors
Ormazabal
reserves the right to fi t impact detectors (or
ask for them to be fi tted) in its transformers, in order to
provide evidence of circumstances that may damage the
transformer substation during transport.
In accordance with Standard
IEC 60076-1
, section
5.7.4.2 Acceleration during transport
, all
Ormazabal
transformers installed in
mb
.m are designed and built to
withstand accelerations of at least 1 g in all directions (apart
from gravity acceleration in vertical direction) without any
damage.
If transport is not managed by
Ormazabal
, or is not carried
out under its responsibility, and accelerations in excess
of 1 g are expected during transport, all accelerations
and frequencies must be defi ned in the order, and the
transformer must be designed in accordance with these
values.
Ormazabal
shall not be liable for any damage during
transport whenever there is evidence of transport
conditions that exceed the values defi ned in the standard
or those specifi ed when requesting the off er and/or order
for the product.
2.2.4. Responsibility
Whenever the conditions described in this document are
not met,
Ormazabal
reserves the right to reject liability
for any damage caused to
mb
.m while transporting and
handling.
2.2.5. Packing
The
mb
.m medium voltage switch enclosure is transported
from the factory with polyurethane corner pieces on the unit.
The transformer includes the protection elements set out in
the general instructions (for
Ormazabal
transformers, see
the manual
IG-168
(up to 3150 kVA) or
IG-287
(> 3150 kVA).
These protection measures must be removed once the unit
is installed and before its commissioning.
