Project Details

This project we conducted High Voltage and Low Voltage electrical installation works required
to establish a new High Voltage Feeder line which connected from existing High Voltage
infrastructure to a new MCC panel and pump station. The installation works typically
entailed the following:

a. Installation of HV aerials, switchgear, transformer and associated support systems to poles;
b. Installation of an earth grid system;
c. Installation of switchboard MCC-51;
d. Installation of HV and LV cabling and associated cable support systems
e. Installation of level transmitter and cabling of instrumentation.
f. The earthing Matt underneath the MCC board was bonding to the main earthing conductor using thermoweld techniques
