Übersetzung für "Isolationsvermögen" in Englisch

A contamination layer deposited on the surface of the insulator impairs the electrical insulation capacity.

The disadvantage of the pentanes is their somewhat poorer insulation performance compared with CFCs.

The insulator then no longer ensures that a sufficient amount of insulation is provided.

This impermeability increases the insulation capacity of the concrete component.

Its fleece is made of microfibre, napped on both sides and provides great insulation.

For example, impact toughness, flexural strength, hardness or electrical insulation capability can be improved in this way.

By way of example it is possible in this way to improve impact strength, flexural strength, hardness or electrical insulation capacity.

The inside of the bag is made out of metallized PE, known for their very good insulation.

Test procedures have been adopted for devices whose insulation characteristics cannot be fully evaluated.

The performance and life expectancy of a vacuum insulation panel is determined by a number of factors.

The higher this value, the better the insulation capacity in relation to volume.

If a fault reduces the insulating capacity at a point on either side of the sheet 4, a relay (not shown) is arranged to arrest the forward motion of the sheet 4 in such a way that the fault point will be located in the region between the two electrode devices at a predetermined distance from the roll pair 7a, 8a.

Recently, very thin batts have been developed which provide excellent insulation properties and are thus very popular in the fashion industry.

The dielectric strength of spark gaps 15, i.e. the field strength at which the insulating power between the electrodes of the gap disappears, measured in kV/cm, must be smaller than the dielectric strength of protective networks 16 within circuit 6.

Regarding the embodiment of the continuous conveyor belt 33, there are various possibilities depending on the thickness and the insulating power of the sheets 34 to be treated.

Moreover, the distribution of the insulating material between the two plates can be deliberately influenced by recesses protrutions being worked in, into which a greater volume of insulating material can be received and consequently the insulating capacity of the heat shield can there be locally increased, which can be advantageous for certain uses.

In particular, the combination of the following properties: high thermal conductivity, high electrical insulating capacity, low expansion coefficient and high thermal-shock resistance, recommends the material according to the invention made of dense, pure AlN for use as a substrate in high-efficiency electronics as, for example, as small mounting plates for semi-conductor elements or electronic circuits.

An important advantage afforded by the invention resides in that electrically insulating coatings having a high insulating resistance can be applied to sheet steel in a simple manner and that the seam welds holding the stacks of sheets together can be formed at high speed.

The latter have a limited insulation capability which may lead to quite dangerous situations since, for example, after a first response of the overvoltage arrester, its insulating resistance may drop considerably.

Rather than the insulation barriers being spaced apart continuously in a manner running purely in a radial direction, the radial, that is to say the shortest, insulation path always has a portion through the material of the insulation ring, for example, pressboard, and a portion through oil, with which the interior of the spherical cap can be filled in the operating state, which has a positive effect on the insulation capacity.

The sharp-edged regions arising as a result of the slots are not disadvantageous for the insulation capacity insofar as they are arranged alongside one another at a small distance of a few millimetres and in this way nevertheless a homogeneity can also arise in the distribution of the electric field.

Here as well the effect occurs that purely radial spacing-apart by the insulation material is not effected and a tangential component is present, which can improve the insulation capacity in the space between the conductive element and the first insulation barrier. The space is oil-filled in the operating state, and the radial displacement of the electric field into the adjoining oil paths can be minimized.

Specifically, the oblique connecting web formed by the trapezium shape runs at a fixedly defined angle towards the first layer 12, rather than—as in the case of a sinusoidal form—at an arbitrarily acute angle, as a result of which the adjoining channel-like cavities 18, 20 in the connection location region would be fashioned correspondingly acutely and can be difficult to fill with oil, both of which adversely affect the insulation ability.

Because of their advantageous properties such as high compressive strength and flexural strength, low specific weight, high corrosion resistance, high use temperatures, low thermal expansion and very good electrical insulation properties, ceramic moldings are being used to an ever increasing extent in diverse products, inter alia also for the production of components for the electrical industry.

The electrical insulation capacity of the insulators is tested in accordance with a rain test to IEC 60/1 (1998), instrument specification IEC 383-1=VDE 0446, Part 1, May 1997.

A liquid-phase 35 sintered SiC (LPSSiC) which has been introduced into the market by Wacker-Chemie GmbH under the brand name EKasic T exhibits a virtually pore-free, fine grained microstructure (mean SiC grain size approx. 1 ?m), a flexural strength of approx. 600 MPa, a fracture toughness which is 40 to 60% higher than that of solid state sintered SiC (SSiC) and a higher electrical insulating capacity (cf. Table 1).

Because of its good insulation capacity the volcanic ash layer is made as thick as possible while allowing the leakage barrier to be made sufficiently thick so as to provide an optimum service life for the pot.

Volcanic ash has approximately the same thermal insulation properties as moler brick and, for this reason, pots which are by far the greater part clad with volcanic ash have a sufficiently large heat insulating capacity.
