Class 3 Insulating Gloves Set

Class 3 Insulating Gloves Set – High-Voltage Electrical Protection for Linemen & Industrial Technicians

Xi'An PPE MAX Co., Ltd has been manufacturing workplace safety equipment since 1956. The Class 3 Insulating Gloves Set is engineered for electrical workers operating at voltages up to 26,500V AC. Each set includes one pair of cotton liner gloves, one pair of Class 3 rubber insulating gloves, one pair of leather protector gloves, and one canvas storage bag — a four-component system built to meet ASTM D120, ASTM F496, ASTM F696, and IEC 60903 standards.

What Is This Product?

This this product is a PPE system built for one job: keeping electrical workers safe from voltages up to 26,500V AC. Each set must pass a proof test at 30,000V AC.

Rubber gloves on their own do give dielectric protection. Cuts, wire strands, and sharp tool edges can still ruin them. That is why the set format exists. Mechanical trauma hits the leather protector first, before it ever reaches the rubber layer. Moisture gets handled by the cotton liner, and comfort holds up through long shifts. Between jobs, the canvas bag keeps the whole set clean, dry, and stored the right way.

FeaturesGreen Label Identification

The green label is the ASTM and IEC designation for Class 3. It confirms the glove is rated for 26,500V AC — distinct from Class 2 (orange, 17kV) and Class 4 (red, 36kV). Confirming label color before every use is a basic safety step, not an optional one.

Dual Material Options

For close, detailed work, Type I natural rubber gives you better flexibility and tactile sensitivity. Ozone and UV degradation are the weakness of plain rubber, and Type II EPDM/Salcor resists both. That makes it a fit for outdoor utility lines and substation environments, where corona discharge produces ozone. Which material you pick comes down to the work environment itself.

Chemically Treated Leather Protector

The leather protectors are chemically processed to reduce water absorption. They are sized to maintain the required cuff gap between the leather and rubber cuff — a gap that prevents electrical flashover along the glove surface.

Wall Thickness for Dielectric Integrity

At 2.3mm to 2.9mm, the rubber glove wall sustains the dielectric strength required at Class 3 voltages while still allowing enough hand movement for tool operation.

How Each Component Works Together

The main electrical barrier comes from the rubber glove. Punctures and scrapes can ruin that insulation. A leather protector guards against them. Hands stay dry thanks to the Class 3 Insulating Gloves Set cotton liner. Dry hands mean better grip and more comfort over a long shift.

Storing the full set in the included canvas bag — fingers pointing up, hung in a cool dry location — helps extend glove service life and protects the rubber from UV and thermal degradation between uses.

Applications

Utility Grid Transmission and Distribution

Linemen use this set for maintenance on distribution lines where voltages exceed the Class 2 limit of 17kV but remain within the 26.5kV Class 3 range. It is suited for bucket truck and pole-climbing operations.

Substation Switchgear Operations

Some techs work on high-voltage switchgear, transformers, and capacitor banks. For them, Type II versions make sense. Corona discharges are common in substations. These gloves hold up against the ozone those discharges give off.

Industrial High-Voltage Maintenance

Steel mills, mining sites, and big data centers often run their own step-down substations. This set lets them keep workers safe. It gets used during fault testing and for routine checks of the infrastructure.

Certifications and Standards Compliance for Class 3 Insulating Gloves Set

We make these Class 3 rubber insulating gloves to meet ASTM D120 and IEC 60903. The leather protectors comply with ASTM F696. For testing, we follow ASTM F496. That standard covers the electrical retest you must do every 6 months while the gloves are in service.

Packing

Each Class 3 Insulating Gloves Set ships with:

• 1 pair cotton liner gloves
• 1 pair Class 3 rubber insulating gloves
• 1 pair leather protector gloves
• 1 canvas storage bag

Packing is done so the rubber gloves cannot be squashed or folded in transit. That keeps their dielectric integrity intact before the first use.

After-Sales Support

Documentation comes with the product, along with compliance certificates. We also give technical guidance on storage intervals and electrical retesting schedules.

FAQ

Q: What is the electrical test interval for this products?

A: OSHA and ASTM F496 say rubber insulating gloves in service get an electrical test every 6 months. Gloves kept in storage need it every 12 months. Whatever the testing status, check the gloves by eye before each use.

Q: Can the rubber glove be used without the leather protector?

A: No. ASTM F496 requires that leather protectors be worn over rubber insulating gloves to prevent mechanical damage. Using the rubber glove without the leather protector is not permitted under the standard's safety requirements.

Q: What does the green label indicate?

A: Green identifies Class 3: a maximum use voltage of 26,500V AC. Orange identifies Class 2 (17kV). Red identifies Class 4 (36kV). Always verify the label color before beginning work.

Q: What is the practical difference between Type I and Type II gloves?

A: Type I is natural rubber. It bends more, but ozone resistance is lower. Type II is EPDM/Salcor. It works for outdoor utility jobs and substations, where ozone and UV exposure are constant. The choice comes down to where the gloves are used.

Q: Between uses, how should the set be kept?

A: Put the whole set in the canvas bag that comes with it. Point the fingers up. Hang it or store it in a cool spot. That spot should also be dark and dry. Keep the set out of sunlight. Heat sources and steam also break down rubber, so keep it away from those too.

Q: Is the set's electrical rating changed by the cotton liner?

A: No. Inside the rubber glove sits the cotton liner. The dielectric rating is not affected at all. Its only jobs are to handle moisture and keep the wearer comfortable during extended shifts.
