Frequently asked questions
What does a cable jointer do?
A cable jointer is a certified specialist who joins, terminates and tests power cables. In Singapore, cable jointers work across LV cables (up to 1kV) and HV cables at 6.6kV, 11kV and 22kV — using heat-shrink, cold-shrink, pre-moulded, plug-in (separable connector) and resin cast joint kits.
Are your cable jointers SP Group approved?
Yes. Our cable jointers hold the SP PowerGrid permit, which requires yearly assessment to maintain. We are also manufacturer-certified on Raychem, NKT, Pfisterer, 3M and Cellpack joint systems used across the Singapore distribution network.
What voltage range do you cover?
The full Singapore distribution range — LV (230V/400V), then HV at 6.6kV, 11kV and 22kV.
Do you do 22kV cable jointing in Singapore?
Yes. 22kV cable jointing and termination is one of our core services — on XLPE and PILC cables, single-core and three-core, copper and aluminium.
How fast can you respond to emergency cable jointing?
We run on-call cable jointer teams for emergency response across Singapore. Typical mobilisation is within hours of confirmation, depending on site access and isolation.
Do you also test the cable after the joint?
Yes. Every joint is closed out with IR testing as a minimum, and VLF or Hi-Pot withstand testing for HV joints — with a full test report.
Do you cover all of Singapore?
Yes. We serve all regions of Singapore — Central, East, West, North and North-East — including Jurong, Tuas, Changi, Woodlands, Tampines and all industrial estates.
