SG / SGC / SGE dielectric gloves class 00 and 0 (up to 1000 V) and protective over-gloves

SG / SGC / SGE dielectric gloves class 00 and 0 (up to 1000 V) and protective over-gloves

Country: Spain · Model: SG / SGC / SGE

For work under voltage up to 1000 V there are latex gloves of class 00 (SG-25, working voltage 500 V AC) and class 0 (SG-50, 1 000 V). They are used in panels and on 0.4 kV cable lines, and for servicing solar plants and batteries of hybrid and electric vehicles.

Standard: IEC 60903 / EN 60903
Class 00 (SG-25): working voltage 500 V AC, proof test 2 500 V, withstand 5 000 V; thickness < 1.1 mm; categories AZC
Class 0 (SG-50): working 1 000 V AC, proof test 5 000 V, withstand 10 000 V; thickness < 1.6 mm
SGC COMFORT: ultra-thin, class 0, high-purity natural latex, mechanical protection per EN 388

Description

The gloves comply with IEC 60903 / EN 60903, and the class is determined by thickness and proof test voltage, because thicker latex has higher resistance. The SG-25 is tested at 2 500 V with a withstand voltage of 5 000 V and a thickness below 1.1 mm, and the categories AZC mean resistance to acid, ozone and very low temperature. The SG-50 has a proof test voltage of 5 000 V, a withstand voltage of 10 000 V and a thickness below 1.6 mm. The latex has a tensile strength from 16 MPa, elongation from 600 %, puncture resistance from 18 N/mm and permanent set up to 15 %, cold resistance is checked by holding for 24 h at −40 °C, and a flame resistance test is carried out separately. Leather SG over-gloves of grain cowhide with a 10 cm cuff are worn over the latex, and they take the abrasion, cuts and punctures. The gloves are stored in SG-35, SGP, CGS cases or in the SG-36 bag.

How to choose

The ordinary SG-25 and SG-50 are chosen by the voltage of the installation, 500 V or 1 000 V AC. When high tactile sensitivity is needed, the ultra-thin SGC COMFORT of class 0 made of high-purity latex with mechanical protection per EN 388 is used. The thin composite SGE of class 0 combine electrical, arc and mechanical protection per EN 388, hence the "3 in 1" designation. For work above 1 kV gloves of higher classes, from SG-10 to SG-40, are needed.

FAQ

How do class 00 and class 0 dielectric gloves differ?

Class 00 (SG-25) is thinner, below 1.1 mm, and rated for 500 V. Class 0 (SG-50) has a thickness below 1.6 mm and a working voltage of 1 000 V, so in a 0.4 kV network it gives a larger margin.

How are latex gloves checked for punctures before work?

The SG-117 pneumatic tester feeds pressurised air into the glove and finds punctures before the electrician touches live parts.

What is worn under dielectric gloves for arc protection?

Fire-resistant SG-37 Nomex gloves per EN 407 are worn under the latex, and they keep molten latex from reaching the skin. Another option is the composite SGE of class 0 with arc protection.

What sizes of class 00 and 0 dielectric gloves are made?

SG gloves are made in sizes from 7 to 12, so they can be matched to the hand of every electrician in the crew.
