Class 4 Insulating Gloves – HV High Voltage Gloves 36,000V (33kV 36kV)
Insulating Gloves | Class 4
CATU’s Class 4 insulating gloves provide electrical hand protection when working near live voltages up to 36,000V. HV high voltage gloves have been tested up to 54,000V and are certified for use up to 36,000V.
All CATU insulating gloves are individually tested and provided in a sealed plastic bag for use with several sizes available from size 9 to 12.
CATU offer a range of Class 4 gloves depending on the requirements including:
- CATU CG-4 Insulating Gloves (EN 60903)
- CATU CGA-4 ASTM Insulating Gloves
- CATU CGM-4 Mechanical Composite Insulating Gloves
Should you require any technical support to select the correct insulating gloves for LV MV HV power systems including 11kV/33kV please contact us – download the Sizing Guide to ensure a comfortable and correct glove fit.
Class 4 Insulating Gloves
CATU CG-4
CATU CG-4 insulating gloves manufactured from rubber are for use with silicon leather glove covers and do not provide mechanical protection.
CG-4 gloves are fully compliant with EN 60903 and IEC 60903 and have an RC classification for resistance to acid, oil and o-zone and low temperatures.
CATU Insulating Glove Part Code | Class | Voltage | Category | Total Length | Glove Colour |
CG-4-(****)-NR | 4 | ≤ 36,000V | RC | 410mm | Bi-colour: Red outside, Natural inside |
(****) Complete by size codes 09 to 12
CATU CGA-4 Class 4 ASTM Insulating Gloves
CATU CGA-4 ASTM Class 4 insulating gloves are fully compliant with the stricter ASTM standard (ASTM D120) and are made of a specially treated rubber which to ensure high dielectric characteristics.
CATU Insulating Glove Part Code | Class | Voltage | Type | Total Length | Glove Colour |
CGA-4-(***)-NB | 4 | ≤ 36,000V | I | 16″ | Bi-colour: Black outside, Natural inside |
(***) Complete by size codes 09 to 12
CATU CGM-4 CLASS 3 Mechanical Composite INSULATING GLOVES
CATU CGM-4 insulating gloves have higher mechanical properties than the CG range and do not require leather overgloves – this standard covers electrical insulating gloves with additional integrated mechanical protection referred to as “composite gloves”.
CGM-4 gloves are fully compliant with EN 60903 and IEC 60903 and have an RC classification for resistance to acid, oil, o-zone and low temperatures. Gloves are also arc flash tested to IEC 61482-1-2 Class 2 and ASTM F2675/F2675M.
CATU Insulating Glove Part Code | Class | Voltage | Category | Total Length | Glove Colour |
CGM-4-(**) | 4 | ≤ 36,000V | RC | 410mm | Bi-Colour – Orange outside, natural inside |
(**) Complete by size codes 09 to 12
Class 4 Glove Standards
EN 60903 is the European standard which classes and categorises Class 4 insulating gloves according to level of protection against electrical shock. Both CATU CG-4 and CGM-4 are compliant with this European standard providing the following voltage exposure withstand:
- AC 36,000V
- DC 54,000V
ASTM D120 standard and specification covers manufacturing and testing of rubber insulating gloves for protection of workers from electrical shock – CATU CGA-4 gloves are compliant with this American standard.
