Glossary

Bending cycle

Number of bends repeated in the drag chain (How often was a cable

actively stressed during testing or during application?)

Bending radii

Permissible radius for occasional or constant bending of cables. The

bending radius is defined as a multiple of the cable diameter. The con-

struction of the cables determines the minimum permissible bending

radius, which allows it to be increased or reduced. The permissible

bending radii must be adhered to when laying power lines and cables.

The standard values are between 15 x D and 30 x D, depending on

construction type and regulation. D is the outer diameter of the cable.

(At Lapp: ÖLFLEX

FD with 5 x D or 7.5 x D).

Bending test at low temperature

Cold flexibility test for cables. A cold cable is wrapped around a pin and

no cracks may occur in the insulation.

Binary

Property restricted to just two values.

Bit

The smallest unit for representing binary data, significance either 0 or

1. It is the basic unit for transmission information in digital systems. A

byte is a group of 8 bits.

Bit error rate, BER

Ratio of error bits to the overall number of bits received during a spe-

cific period.

Blue cable

Cable for intrinsically safe systems in hazardous locations. The compul-

sory colour code here is blue, RAL 5015. (For Lapp, ÖLFLEX

EB. These

cable types are also available with shielding, e. g. ÖLFLEX

EB CY,

UNITRONIC

EB CY).

Braid angle

Variation in degrees between the longitudinal axis and the wire routing

within the braid.

Braiding

Arrangement of interlaced wires or threads forming part of the struc-

ture of a cable. Copper wire braiding is used for screening, while

braiding made of textile, plastic thread or steel wire performs support-

ing or carrying, i. e. mechanical, functions. Braiding can be close or

wide meshed (coverage density in percent) with different angles of

twist.

Breakdown

This refers to electrical breakdown between two conductors or a con-

ductor in water during the testing process, when the insulation can no

longer withstand the constantly increasing voltage (breakdown voltage)

or if a fault in the insulation results in a breakdown within a specified

time at a constant voltage.

Breaking load, ultimate load

The product of nominal cross-section and tensile strength is the break-

ing load.

British Standard Wire Gauge

Also known as NBS (New British Standard), SWG (Standard Wire

Gauge), Legal Standard and Imperial Wire Gauge. A modified version of

the Birmingham Wire Gauge, a standard from Great Britain valid for all

wires.

Broadband

Transmissions in which the signals are transmitted by a high number

of oscillations per second (glass fibre technology).

Abbreviation for British Standard. Standards body for Great Britain,

similar to VDE in Germany.

BSI

Abbreviation for British Standard Institution – Great Britain.

Bundle

Several cores or pairs that are stranded into a group and in turn make

up one element of a strand assembly.

Bus system

The bus system is a system of cables that transmits information and

data.

Cable

Combination of several cores with protective layers (sheath) or sheath-

ing of a single core. The sheathing protects the cores against all kinds

of harmful influences. Cables are used to transport electric current

(power cables), transmit information using an electric current (data

cables) or to transfer information using light waves (light waveguide

cables). The term line is also commonly used, depending on the appli-

cation. It is not possible to exactly delineate the two terms. In general,

the term “cable” is used for installations outside buildings. In practice,

however, the terms are used interchangeably. Combination of any

number of cores under a sheath.

Cable carrier

An assembly of linked, hinged support elements for directional, dynamic

routing of all types of flexible bending power cables.

Cable data

The cable type file is part of the CAE software from ePLAN

. The cable

type file defines the number of cores, their colour code, the PE core

and the screening for all cables. In the Lapp item master data for

ePLAN

, the cable type is assigned to the relevant item. This means

that when a Lapp item is selected, each core is automatically assigned

the appropriate colour code in the ePLAN

circuit diagram.

Cable gland

The brand name is SKINTOP

at Lapp. A cable gland is a device that is

designed to guide a cable or an insulated conductor into a sheath and

provides a seal and a restraint mechanism. It can also have other func-

tions, e. g. kink prevention, strain relief, potential equalisation, earth-

ing, insulation or a combination of these.

Cable gland size

The following sizes are currently defined in EN 60562: M 12 x 1.5;

M 16 x 1.5; M 20 x 1.5; M 25 x 1,5; M 32 x 1.5; M 40 x 1.5; M 50 x 1.5;

M 63 x 1.5; M 75 x 1.5; M 90 x 2; M 110 x 2. M stands for metric.

Cable print

Coloured marking on the outer sheath of individual elements or cables

using symbols, names and other markings.

Cable set-up

Describes (from inside to out) the materials used for cables, their

design and properties and the position of the individual elements.
