Electric Insulated Floor Mats in Substations

04/28/2006 9:17 AM

Electric insulated mats are used in front of high voltage switchboards at substations, for safety. Both rubber and PVC insulating mats are used. Since rubber mats are not weather/ moisture proof, is it safer to use PVC?
Request for more information,relevant IEC specifications, on this, if any.

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"

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 .

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.

Yes correct and it has been proved, BIS changed the old standard IS:5424 ( insulating Rubber Mats for Electrical Insulation Purposes ) to IS:15652/2006 ( Insulating PVC Mats for Electrical Insulation Purposes).

Sir, I would like to inform you that the BIS has not mentioned PVC anywhere in the Standard and the name for IS:15652-2006 is "INSULATING MATS FOR ELECTRICAL PURPOSES" and NOT "Insulating PVC Mats for Electrical Insulation Purposes".One can obtain the standard booklet from BIS Office or logon to and download the IS:15652 standard on very nominal charges which will give you clarifications on Insulating Mats for Electrical Purposes. And I request not misguide the readers as this forum is meant for educating the readers and not for misguiding them. PLEASE PLEASE DON'T MISGUIDE THE READERS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

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.

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.

First of all I suggest you to clam down & don't make sarcastic comments!!!

We are here to discuss about Technical issues related to PPE not to make any personal comments. You are taking things personally.

Now, coming back to the topic there is a huge difference between TPE & PVC. You will here be surprised to know even Rubbers come under a class of Plastics but off course they are not PVC because that is a separate class of Plastics.

The reason I have chosen Reference of Wikipedia because it is the most renowned encyclopedia, whose facts & figures are accepted World-Wide needn't to mention over any Local/National standards.

Again please refer to this link to get fair Idea about what I just explained- http://en.wikipedia.org/wiki/Plastic#Fossil-based_plastics

Remember, PLASTIC not always mean PVC, it mean "everything capable of being shaped or molded".

Further clarification/suggestion with Proven facts are welcomed, Your work in terms of BIS standards know-how is appreciated!

Thanks for your time.

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.
