The abbreviation code reflects the type, nature and structure of a wire or cable in a simplified and abbreviated form. It is divided into several subgroups which, when read from the inside out, reflect the structure of a wire or cable. (All information without guarantee)
Abrasion resistance
Property of a cable, wire or material to withstand surface wear. (All data without guarantee)
Actuator
An actuator is used to convert an electrically available signal into mechanical energy or other physical sizes. It is therefore the counterpart to the sensor, which converts energy into electrical signals. The actual action of the actuator is called actuation. It describes the generation of a movement or deformation. An actuator can, for example, be a valve in a control chain that opens or closes when an electrical signal is applied.

AES / EBU
Informal name of a digital audio standard created jointly by the AES (Audio Engineering Society) and the EBU (European Broadcast Union) organisations. The standard defines the transmission characteristics of the digital signal in order to simplify communication between devices. (All information without guarantee)
Ageing
Refers to the change in properties (preferably tensile strength and elongation) of a material as a function of time under specific conditions such as temperature, UV radiation, ozone influence, chemical and thermal stress, etc. (All data subject to change). (All data without guarantee)
Air section
Shortest air gap between two conductive parts. Clearances are specified by the rated impulse voltage. (All data without guarantee)
Alternating current
Alternating current is a current flow that periodically changes direction from positive to negative. The prerequisite for alternating current is an alternating voltage source such as a generator. (All information without guarantee)
Aluminium
If a copper conductor is replaced by an aluminium conductor with the same conductivity, it weighs only about half as much as the copper conductor, even though it has 1.6 times the cross-section. However, the larger cross-section requires increased material consumption of all subsequent components (insulation, sheaths, armouring, protective sheaths). (All data without guarantee)
Aluminium jacket
An aluminium sheath is lighter than a lead sheath. It has better conductivity and greater strength, but requires a plastic sheath as corrosion protection. (All data without guarantee)
Ambient temperature
The temperature of the air surrounding the equipment, determined under specified conditions. (All data without guarantee)
Antenna cable
Antenna cables are coaxial high-frequency cables for receiver connections, house distribution networks and individual antenna systems. The main areas of application are: reception and distribution systems for radio and television broadcasting. Antenna cables must ensure low-reflection signal transmission.
Anti-ageing agent
As anti-ageing agents have a colouring effect on rubber compounds, they are usually only used for dark compounds. They prevent premature embrittlement of the compounds. (All information without guarantee)
Approved wires
Control and data lines with approvals, standards. Examples: VDE, UL/CSA, GOST-R (All information without guarantee)
ASI
Short for actuator-sensor interface. With ASI, only linear actuators and sensors in the lowest fieldbus range are linked to the first control level.bus system for the lowest automation level. Enables the simple connection of sensors, actuators and integrated systems to the first control level. See - Master/slave principle. Up to 248 binary inputs and outputs per network, information and energy on one wire, reverse polarity protected connection technology, 100m cable length or up to 300m with repeater, free tree structure of the network, protection class up to IP 67, cycle time <5ms, high interference immunity and fault tolerance. (All data without guarantee)
Assembly
Correct assembly of connection technology is important to ensure that connectors fulfil the guaranteed technical properties required for an application. Tighten the axial screw with a torque spanner. This is the only way to ensure a gas-tight, largely corrosion-protected connection of the copper stranded wire and consistently good transmission properties throughout the entire service life of the connector. (All information without guarantee)
Asynchronous transmission mode
The asynchronous transmission mode can realise different transmission speeds and network expansions in communication networks. (All information without guarantee)
ATEX
Atmosphére Explosible. See -> Explosion protection. The term Atex is used colloquially as a synonym for the two EC explosion protection directives, namely Directive 94/9/EC [ATEX 95] and Directive 1999/92/EC [ATEX 137]. They concern the nature of components, equipment and protective systems for use in potentially explosive atmospheres and the minimum requirements for the installation and operation of systems in which explosive atmospheres are present. (All information without guarantee)
Atex approval
Atex approval is required for the intended use of devices and protective systems in potentially explosive atmospheres. (All information without guarantee)
Auto-Crossing
Allows automatic crossing of the transmit and receive lines on twisted pair interfaces. This allows the application to use 1:1 wired and cross over cables equally. (All information without guarantee)
AWG
American Wire Gauge. AWG = American Wire Gauge = coding for the conductor cross-section. The smaller the AWG number, the larger the conductor cross-section. If the AWG number is smaller, the wire diameter becomes larger. The actual values (mm) depend on the wire resolution, depending on whether a rigid conductor or a stranded wire is used.
