HT cable specialists, built in Singapore.
Powerhowz Pte Ltd is a Singapore-based electrical contractor focused on the high-tension end of the grid. We terminate, joint, test and commission HT cables — and we're SP Group permitted to do it.
Direct, technical, quietly reliable.
Powerhowz was founded by cable jointers, not salespeople. The team has worked on substations, MRT alignments, datacentre feeders and industrial estates across the island. We know what a clean joint looks like and we know what an SP audit asks for.
We work direct with main contractors, EPCs, facility owners and procurement teams. No layered subcontracting. No surprise variations. A quotation arrives within 48 hours of a spec sheet — and the team that quotes the work is the team that does it.
Three things we don't compromise.
Our standards are short, practical, and the same on every project.
Permit-grade work, every joint.
We don't run any cable jointing without an SP-permitted technician on the team. No exceptions, no shortcuts.
Documented before energising.
VLF and sheath tests are run, signed and handed over before a circuit goes live. The paper trail is part of the work.
Direct line to a real engineer.
When a contractor calls, an engineer answers. No call-tree, no account manager filtering questions back to the field.
From substation to switchroom.
We work across construction, industrial and infrastructure projects in Singapore.
