There are 2 main types of insulating gloves i) Latex Gloves provide high dielectric performance and must be used with leather overgloves for mechanical protection, ii) Composite Gloves provide superior mechanical protection against punctures and tears eliminating the need for overgloves. Wearing suitable PPE to protect electrical engineers, cable jointers and linesmen against dangers posed by exposure to electric cables and circuits is essential. Insulating gloves must be flexible and durable with high dielectric strength compliant with IEC 60903. Insulating rubber gloves conform to IEC 60903 standard. IEC 60903 standard insulating rubber gloves are subject to dielectrical, mechanical resistance and ageing tests - composite and rubber insulating gloves are available to prevent against electric shock hazards. Insulating gloves are used by LV-HV cable jointers, electrical engineers and overhead linesmen and are approved by UK utilities including EDF Energy. Typical applications include : low voltage and live-working up to 1kV (Class 0 Insulating Gloves), live line working on overhead lines (Class 1, 2, 3, 4 Insulating Gloves), electrical switching and also when operating underground moling machines.

Insulating rubber gloves
An essential choice for safety!
Compliance.
CHARACTERISTICS OF SYMBOLS
Insulating gloves offer personal protection against electrical shocks
when working on or near live wires.
They must comply with the IEC 60903 and EN 60903
standards. As a result, they undergo various voltage,
ageing, and mechanical testing.
• Label with a double triangle symbol
IEC 60 417-5216, suitable for work
on live wires.
• Label with a mechanical hammer
symbol, indicating composite gloves.
The gloves are individually tested and sold in
a sealed plastic bag.
All our gloves provide
greater comfort and
hygiene when used.
Glove Types, Classes, and Categories.
There are 2 main types of insulating gloves:
- Latex gloves provide high dielectric performance. They must be used with leather glove covers for mechanical protection.
- Composite gloves offer superior mechanical protection against punctures and tears. They eliminate the need for overgloves.

Inspection and Storage of Insulating Gloves.
All insulating gloves must be visible inspected after
inflation and before each use.
For Classes 1, 2, 3, and 4: Even when in storage, a glove cannot be used without having been tested within the last six
months. Normal testing periods are between 30 and 90 days.
For Classes 0 and 00: The tests consist of an air inflation test and a visual inspection when the glove
is inflated. The dielectric test is not required, but it
may be performed at the owner's request.
An inspection of the inside of the gloves is also recommended.
Gloves should be stored in their packaging, without being compressed or folded. They should not be stored near a heat source
with a temperature of 10 to 21°C.
