Abstract: An arrangement (1) for the electrical earthing of an electrically conducting cable (2) with an outer insulating protective cover (3). The arrangement comprises a receiver (4) and a drop unit (5). The receiver (4) comprises a bottom element (6), two opposing side elements (7a, 7b), two opposing open sides (8a, 8b). The bottom element (6) and the side elements (7a, 7b) form together a cleft (9), which cleft (9) is the receiver of the said cable (2) for earthing. The drop unit (5) comprises not only a connection to earth (10), but also a penetration means (11), which connection to earth (10) and penetration means (11) are in electrical contact with each other.

Abstract: Device for arranging cables in a junction box extractable from a chassis. Between the junction box (1) and the chassis (2) there is a conduit (5) into which the cables (7) are run from the front viewed from the direction in which the box is extracted from the chassis (2), whereby the length of the cable (7) in the chassis (2) is chosen so that the junction box (1) can be drawn out of the chassis (2) for a distance determined in advance.

Abstract: The invention relates to an insulator for an electrical conductor provided with an outer shield, especially a so-called coaxial cable or shielded twin cable, in order to achieve an insulation at the shield that insulates against DC and low frequency AC signals transforming through the conductor and that includes a first and a second element (3,4) formed from electrically conducting material that by means of a dielectric (5) are electrically insulated and delineated from one another. and that are intended to be connected between an interruption at the shield or between the shield and an external earth connection.

Abstract: The invention relates to a portable, battery-driven device for measuring heat transfer coefficients (k-values). It uses an amplifier (1), which forms the quotient between the inner temperature minus the inner wall temperature on one hand and the inner temperature minus the outer temperature on the other hand. The temperature values of the first-mentioned substraction are obtained by thermal elements (7, 8), which are connected to the device. The difference according to the second one of the substractions is adjustable connected in a feed back circuit of the amplifier (1). The output quantity of the latter is supplied to an instrument (3) graduated in k-value. The thermal element for the measuring of the inner wall temperature can be provided at the tip of a probe (9), and may consequently be conveniently applied to different places of a wall to be investigated.
