Electrical-Insulating Rubber Sleeves

Electrical-insulating sleeves are made of dielectric rubber and meet ASTM D1051 specifications to protect workers from electrical hazards. They are worn with electrical-insulating rubber gloves and extend protection up the arm. 

Electrical-insulating sleeves are categorized by voltage class (Class) and whether or not the sleeve is resistant to ozone (Type). Voltage class describes the maximum voltage the glove can be used with. Workers should use a voltage class rating that matches the requirements set by their work site. Type I electrical-insulating Sleeves are not ozone-resistant. Type II electrical-insulating sleeves resist cracking and degradation caused by exposure to high levels of ozone that can be found in high-pollution areas. Sleeves should be inspected for pinholes before each use.

class 0 rubber sleeve

Class 0

Class 0 electrical-insulating sleeves are made of dielectric rubber to protect workers from electrical hazards up to 1000VAC. Electrical-insulating sleeves are worn with electrical-insulating gloves and should be tested for pinholes before each use. Workers should use a voltage class rating that matches the     requirements set by their work site.

class 1 rubber sleeve

Class 1

Class 1 electrical-insulating sleeves are made of dielectric rubber to protect workers from electrical hazards up to 7500VAC. Electrical-insulating sleeves are worn with electrical-insulating gloves and should be tested for pinholes before each use. Workers should use a voltage class rating that matches the     requirements set by their work site.

class 2 rubber sleeve

Class 2

Class 2 electrical-insulating sleeves are made of dielectric rubber to protect workers from electrical hazards up to 17,000VAC. Electrical-insulating sleeves are worn with electrical-insulating gloves and should be tested for pinholes   before each use. Workers should use a voltage class rating that matches the requirements set by their work site.

class 3 rubber sleeve

Class 3

Class 3 electrical-insulating sleeves are made of dielectric rubber to protect workers from electrical hazards up to 26,500VAC. Electrical-insulating sleeves are worn with electrical-insulating gloves and should be tested for pinholes     before each use. Workers should use a voltage class rating that matches the requirements set by their work site.
