Insulation board, also called insulation pads, insulation, insulation gasket, insulation blanket.
Insulation is widely used in substation, power plants, substations, laboratory and field charged operation use.
Under the insulation class with glue, insulating mat surface should be no harmful irregularity.
Insulation harmful irregularity refers to one of the following features, namely, destroy the uniformity, smooth surface damage contour defects, such as holes, cracks, local uplift, incision, mixed conducting foreign body, creasing, gap, concave and convex corrugated and casting marks, etc.
Harmless irregularity refers to the process of formation of the surface irregularity.
On the whole insulation board should be randomly selected five or more different points for thickness measurement and inspection.
The micrometer or the same precision of the instrument can be used for measurement.
The precision of micrometer should be 0.
02 mm less than, measure the diameter of the drill is 6 mm, flat presser foot diameter (
Mm, presser foot should be able to exert (
The pressure of the N.
Insulation should be placed flat, in order to make micrometer to measure between is smooth.
Glass fiber with antistatic high mechanical strength characteristics of resin composite materials made of 1.
Beautiful and easy, smooth level off good flatness, smooth surface, no pits.
Good heat resistance and wave resistance, dry, wet electric performance is good;
Bibulous rate is low, not easy deformation.
High mechanical properties and good machinability.
Anti-static performance classification with excellent antistatic effect, can be divided into (
Single anti-static and double-sided anti-static/overall anti-static three)
Single anti-static glass fiber board: a black anti-static, a green insulation, high temperature resistant.
Double-sided anti-static glass fiber board: er for aqua glass fiber, surface black anti-static surface.
Overall anti-static glass fiber board: any parts antistatic values are the same.
Antistatic performance value (
The surface resistance: 10 ^ 6 -
10 ^ 9 Ω proportion of 1.
0 use temperature/performance and heat-resistant up to 180 ℃
