Unpacking and Accepting
Please check whether there is any damage, distortion and crack on the transformer and its
components. With reference to the shipping list or packing list, check the accessories and special
tools. Only after the inspection is finished and the result is acceptable can the installation be
carried out.

Notices for installation:

Before any system connection, be sure the transformer is earthed. The earthing terminal
of the pad-mounted transformer should be a fixed and low-resistance earthing point. If
the earthing resistance does not meet the requirement, resistance reduction measures
should be adopted.


 Before system cabling, please clean all the bushings, bushing seats, terminal cabling
seats and contacting point, to remove all the dust, oil pollution and foreign substances.

 During installation, please close the equipment door and lock it when there is no technician on duty.


 Installation Process

Please refer to the following process for installation:
Prepare the installation base---->lay the HV and LV cables---->equipment
lifting---->equipment fixing---->equipment earthing---->HV and LV cable fixing
(preliminarily)---->HV and LV cable phase process---->prepare elbow cable plug and LV
terminal---->put the elbow cable plug (and lightning rod) into the bushing and connect the LV
cables---->mount the fault indicator and electricity display---->mounting LV sub-assembly.


 Prepare the Installation Base

The basis is composed of reinforced concrete base capable of holding the transformer, the
manhole convenient for cable connections and equipment maintenance, cable support/rack or
earthing sub-assembly. Fore more information about the basis preparation, please refer to the basis
manufacturing instructions provided together with the equipment.


Please be noted that:
1) The basis should be made far from the flat bog area, to avoid water drenching.
2) The base top should be located on a high place and 100~400mm above the ground.
3) Cable supporting rack should be made on the basis and firmly fixed, with certain
mechanical strength to avoid any shaking or loosing.
4) The base should be of sufficient mechanical strength to prevent any sinking, which may
cause equipment damage.
5) The surface of the base should be on the same level and smooth. If necessary, please use
level bar to check the base surface, thus to ensure no equipment distortion will happen
due to poor base conditions. Un-even base surface may makes door opening difficult.
6) The earthing resistance and earthing cross section should meet corresponding national
standards, industrial standards and regulations specified by local power administration
