High-Voltage Withstand Testers

Built with premium fiberglass, insulated rubber, and composite polymers, our tools offer reliable insulation, outstanding mechanical strength, and long-term durability. Whether used for live-line work, electrical maintenance, utility operations, or industrial installations, these high-voltage insulated tools help prevent electric shock and reduce workplace hazards.

FEATURES:

1. Telescopic, compact, light-weight The length is elastic from 354mm to 1005mm, The equipment is light-weight (180g), easy to handle, and handy to carry.

2. High-voltage detectable

The equipment, whether in stretched state is available for voltage detection in high-tension circuits (3.3kV, 6.6kV and 24kV) whether the wires involved are naked or insulated.

3. Low-voltage detectable

The equipment can be used for voltage detection in low-tension circuits (80V ~ 600V) by holding the nameplate portion of the

detecting head. Before-use check can easily be done by plugging in an AC 100V plug socket, without using a tester.

4. Easy to recognize indication

Intermittent lighting in red of a high intensity light-emitting diode and intermittent audible sound of an electronic buzzer are readily recognizable at a full daylight, noisy location.

5. Waterproof

The detecting head, being tightly enclosed, is free from any trouble due to dust, dirt, water or the like.

Suitable for professional electricians, utility workers, renewable energy technicians, and heavy-industry maintenance teams, our insulation tools support safe and efficient operation across a wide range of voltage levels. Each tool is tested for dielectric strength, slip resistance, and heat/cold endurance, making it a trusted choice for electrical safety tools in demanding working conditions.

Front Metal :

To be put in contact with wires, etc for voltage detection.

Test switch :

For checking to see that internal electronic circuit is in order.

Nameplate portion :

For L.V. detection, this portion is to be held by hand.

Grip portion :

Don't touch any portion other than this during H.V. detection.

HANDLING AND MAINTENANCE :

Before use for Voltage detection :

1. Check to see that nothing is wrong with the equipment in appearance and construction.

2. Switch on test switch to check for working of the internal circuit for cautions sake try with a known line for operation.

3. When inspecting a high tension line, hold the grip portion during detecting operation.

Do not touch any portion other than the grip because danger involved.

4. When using the equipment in constructed state for inspecting a high voltage line wear insulating rubber gloves.

5. For voltage detection in a low tension line hold the nameplate portion.

6. If it is necessary at all to carry out voltage detection during rainfall, pay constant attention to the wet condition of the

equipment.

Handling and Safekeeping :

7. Do not subject the equipment to any hard shock by dropping or placing under something.

Do not wipe it with a chemical or the like.

8. Do not leave it on a road site in summer or place it in a hot location in a car or the like.

9. Be sure to keep it clean at all times, and choose a dry location kept away from direct sunlight for safe keeping.

Our High-Voltage Insulation Tools are manufactured under strict quality systems and fully meet international electrical safety standards. Each tool undergoes comprehensive testing to ensure reliable insulation performance, mechanical durability, and long-term safety in high-voltage environments.
