Where the insulated torque wrench fits in Singapore
Insulated torque wrenches belong wherever torque and live voltage meet: switchgear and busbar connections, battery energy storage systems, EV and data-centre power distribution. In Singapore these jobs fall under strict electrical safety rules; therefore, a wrench that insulates the operator and controls torque at the same time is the correct tool.
Pair it with
- All Mountz torque wrenches for non-electrical work.
- Mountz torque analyzers to verify the setting.
- Wrench adjusting keys for setting changes.
Frequently asked questions about the insulated torque wrench
What voltage is the Mountz insulated torque wrench rated for
The insulation protects against voltages up to 1,000 volts, which covers low-voltage switchgear, battery and power distribution work.
What torque range does it cover
Both models cover 4 to 20 N·m, with a choice of 1/4-inch (SLO1/4I) or 3/8-inch (SLO3/8I) drive.
How accurate is it
The certified range follows ISO 6789 at plus or minus 4 percent of the indicated setting.
Where is an insulated torque wrench used
It is used on busbars, switchgear, battery energy storage and EV power systems, in other words anywhere a fastener must be torqued near live conductors.
