Electric Insulated Floor Mats in Substations

If your substation is not weather resistant, neither mat will be safe. I'm not sure if there are IEC or other standards, but there are some users of DC substations that use these. I will try to find a spec.

Further to your comment,I wish to add thatIndoor substation is protected against rains and also provision of positive pressure ventilation and space heaters in switchboards prevent humidity. However,PVC has superior dielectric strength and insulating property,which can provide better safety to operators as compared with Rubber.This needs to be however established through some technical literature,standards. Please help.

Not a lot of detail, but this is the spec text I found for a DC sub: "Provide the switchboard, rubber matting ribbed type with dielectric rating of 40,000 volts, DC and certified as tested and passed, under requirements of ASTM regulations to ensure personnel safety against 8000 volts to ground. Mat shall be continuous length, black color, minimum 1/4-inch thick, minimum three foot (3') wide and extend the full length of entire switchboard. Mat shall be installed full depth of working space." Best I can find, sorry no technical reference.

I would to like to throw some light on the fact that if you go through the BIS specifications for Insulating Mats you will not that BIS has not mentioned PVC word in its specifications. Only RUBBER Mats are being used since years all around the world as insulating mat and are still being used. BIS has mentioned "ELASTOMER" which includes "RUBBER" but not "PVC".

Please go through the links below and it will be justified that only rubber mats serves as better insulating Mats than "PVC"

Hope that the information provided is helpful.

PVC mats are the recent introduction for elctrical insulating application for floorings--

they are avalaible as per latest IS 15652 -2006 specifications in India which has referred to IEC 61111-2002-2006 in its FOREWORD. These ELECTROMAT mats are suitable upto 33 KV .Thickness is only 3mm plus they are fire retardant and acid/alkali/oil proof.They are washable and easy to inastall .we offer the same and have installed electromat in sevaral pertrochemical/engineering/pharmaceutical units.they are easy replacement of traditional rubber mats .

Hi,

Rubber mat shall be provided for 132kV Control & realy panel aslo with a standard thickness of 8 or 10 mm and 1000 mm wide.

As, indiacted it shall be continous for all the coupled panels.

Vardhman insulating switchboard matting is considered as personal protection equipment (PPE), it is specially designed for use in front of open switch boards or high voltage equipment. Used in many industrial plants and factories to protect against electrical shocks. Mats conforming to this standard are highly recommended in all kinds of electric sub-stations, transformer rooms, lift machine rooms, switch rooms, electrical panels, ac plant rooms, x-ray plant rooms, lt/ht labs, around bus bars, generator rooms, etc. as a safeguard to the life of human being due to any possible leakage.

Is it safe to use PVC Insulating Mats, in place of Rubber Insulating Mats for High Voltage Electric Panels?

I would to like to throw some light on the fact that if you go through the BIS specifications for Insulating Mats you will not that BIS has not mentioned PVC word in its specifications. Only RUBBER Mats are being used since years all around the world as insulating mat and are still being used. BIS has mentioned "ELASTOMER" which includes "RUBBER" and NOT "PVC".

Please go through the links below and it will be justified that only rubber mats serves as better insulating Mats than "PVC" all around the world.

Hope that the information provided is helpful.

Why BIS changed the specification from 6mm to 25mm Rubber Mats for Electrical Purposes to 2mm, 2.5mm, 3mm Elastomer Mats, if both are supposed to be composed of RUBBER.

I would like to ask you that you have written "elastomer mats" and BIS has clearly mentioned "it includes rubbers, latex and elastomeric compounds that may be naturalor synthetic or mixture or a combination of both". And PVC is NOT AN ELASTOMERIC MATERIAL it is a THERMOPLASTIC MATERIAL.

Thermoplastic is also an elastomer, although Plastic may or may not be thermoplast.

TPE - Thermoplastic Elastomer is a class to Plastic which exibit properties of both Plastic & Rubber.

For Reference check- http://en.wikipedia.org/wiki/Thermoplastic_elastomer

Does any one know the reason why IS:5424-69 standard has been replaced by IS:15652???

If BIS wanted to replace Rubber Mats by PVC Mats then why would they mention "Rubber" in the composition clause and not "PVC"???

Guess some people dont have time to go through IS specifications and were busy on google looking for illogical support to their statements totally ignoring BIS specifications. I request them to kindly go through them again and dont put up any comments without having any documentary proofs such as BIS specifications as web links are not acceptable to BIS.

Insuulating Mats are to be manufactured as per BIS specifications not "WIKIPEDIA"

You may put up any govt. lab's PVC Mat Type Test Report and prove the fact that PVC is the right material for Insulating Mats.

Sirs,

If my substation & switchboard is 33kV, what class & type of mat should I use.

Need to consider phase-phase as working/rated voltage(33kv) or phase to ground (19kV) only.

Appreciate any advice.
