Electrical insulation mat specifications.
Catu electrical insulating matting is specified and tested to iec 61111 category c with working temperatures to 40 c for the following voltages.
1 1 this specification covers acceptance testing of rubber insulating matting for use as a floor covering for protection of workers.
Insulated mats for electrical purposes are mainly for safety from electrical shock when working in or around environment like high voltage panels sub station power transformer rooms lt ht labs near bus bars near control panels etc.
1 2 two types of matting differing in chemical and physical characteristics are provided and are designated as type i and type ii matting.
High voltage insulation mat are relatively thin mats of thickness 2mm to 3 5 mm made of elastomeric polymers material having a high insulation resistance thus imparting total safety of human being from any leakage current.
Rubber insulating equipment meeting the following national consensus standards is deemed to be in compliance with the performance requirements of paragraph a of this section.
Foreign material remains in place when the insulating material is folded and stretches with the insulating material surrounding it note to paragraph a.
High quality insulating mats with excellent electrical insulation and mechanical.
Catu s electrical insulating matting provide electrical protection for individual and collective protection for workers involved on electrical installations for voltages of 3 3kv 6 6kv 11kv 15kv 20kv and 33kv generally used in conjunction with additional pp such as insulating gloves for worker safety.
