User prepared cables [t-head2]

100 m 4 × 0.14 mm2; twisted pair: EASY-NT-CAB

RJ45 plug:
EASY-NT-RJ45

Crimping tool for RJ45 plug: EASY-RJ45-TOOL.

Calculating cross-section with known cable lengths [t-head3]

The minimum cross-section is determined for the known maximum expansion of the network.

l

=

Length of conductor in m

Smin

=

minimum cross-section in mm2

ρcu

=

specific resistance of copper, unless otherwise stated 0.018 Ωmm2/m

Note
If the result of the calculation is not a standard cross-section, use the next highest standard cross-section.

Calculating length with known cable cross-section [t-head3-col]

For a known conductor cross section the maximum conductor length is calculated.

lmax

=

Length of conductor in m

S

=

Conductor cross-section in mm2

ρcu

=

specific resistance of copper, when nothing else state 0.018 Ωmm2/m
