AD / MA / STE / STM dielectric mats, blankets, insulating stands and covers
Country: Spain · Model: AD / MA / STE / STM
The AD dielectric mat per IEC 61111, the MA blanket, the STE and STM stands, the ST-79 modular plate and covers with clamps for 1000 V separate the worker from the floor and neighbouring live parts. They are used in 0.4 kV switchgear, panel rooms, transformer substations and during live repairs in LV networks.

Description
The AD mat of natural rubber SBR has a density of 1.51 g/cm³, a hardness of 71 Shore A, a tensile strength of 75.5 kgf/cm², an elongation of 362 % and a tear resistance of 20 kgf/cm², and works from −40 to +70 °C. The MA blanket of vulcanised elastomer is brightly coloured so that it is visible in the work area, has category AZ (acids and ozone), a strength from 12 MPa, an elongation of 300 % and a hardness of 60 Shore A. It is tested for puncture, flame resistance, ageing and bending at low temperature. The STE stand for outdoor installation has a rough non-slip platform of 525 × 525 mm of impact-resistant polypropylene copolymer, and the legs of tubes filled with foam per IEC 60855 are fitted with tilting caps and rubber tips. The monobloc STM are made for indoor use and are stacked for storage. The ST-79 plate of impact-resistant polyethylene is assembled from modules of 500 × 500 mm to the required area.
How to choose
For a permanent workplace at a panel the AD mat is enough, on open sites the STE is placed, and the STM where stands are moved often. A large area in front of a row of cells is more conveniently covered with ST-79 modules. Bare conductors are covered with the SP-22 cap, the SP-321 profile or the SP-35 vinyl sheet 0.3 mm thick on SP-39 wooden pegs, and the PA-1.5 and S/PA clamps are rated for 1000 V. A panel taken out for repair completely is earthed with an ECBT portable kit per IEC 61230.

FAQ
To what standard is the AD dielectric mat made?
The AD mat complies with IEC 61111 and works from −40 to +70 °C, so it is suitable for unheated panel rooms as well.
Can a dielectric mat be placed where fuel or solvent spills are possible?
Better not. According to the manufacturer, AD rubber of 71 Shore A hardness is not recommended for contact with hydrocarbons and organic solvents, and has moderate resistance to dilute acids and alkalis.
What size is the platform of the STE insulating stand?
The STE platform is 525 × 525 mm with a rough non-slip surface, and the legs of tubes are filled with foam per IEC 60855.
What is used to replace a fuse safely in a low-voltage panel?
ME-60S and ME-60S-SM handles are made for this, and they are used to remove and fit the fuse without touching it by hand.
