E‑Mobility Instal­la­ti­on

With the paten­ted Woertz Pier­cing cont­act, a poin­ted screw or kni­fe pene­tra­tes the insu­la­ti­on of the flat cable and enters the cable strand. This pro­cess pushes the stran­ded wires apart. The indi­vi­du­al wires are in cont­act with the screw or bla­de sur­face over a lar­ge area, but the stran­ded wire is not cut through like with con­ven­tio­nal cont­ac­ting. The stret­ching of the indi­vi­du­al wires crea­tes a cont­act pres­su­re that favours cur­rent trans­mis­si­on bet­ween the wires and gua­ran­tees low resi­stance values. Fle­xi­ble moun­ting opti­ons and a wide ran­ge of appli­ca­ti­ons are the strengths of this type of contacting.

Plug con­nec­tions are addi­tio­nal cont­act points. Cont­act points are always weak points. Redu­cing the­se to the abso­lu­te mini­mum is what sets this system apart. A plug only makes sen­se whe­re the­re are no high char­ging curr­ents and fre­quent unplug­ging and plug­ging in is to be expec­ted. Howe­ver, the out­go­ing cable is nor­mal­ly fit­ted once and does not even need to be repla­ced when the char­ging sta­ti­on is repla­ced. You sim­ply con­nect it to the new char­ging station.

A plug is more than unneces­sa­ry here and brings with it some major dis­ad­van­ta­ges in terms of ener­gy effi­ci­en­cy and safe­ty. Espe­ci­al­ly when high char­ging curr­ents are pre­sent, as they are in char­ging infras­truc­tu­re, plug con­nec­tions cau­se addi­tio­nal resi­stance, vol­ta­ge los­ses and sus­cep­ti­bi­li­ty to faults. Addi­tio­nal costs for the plug are inclu­ded in the pri­ce of the cable and the junc­tion box.

Instead, Woertz offers pre-assem­bled junc­tion boxes with out­go­ing cables alre­a­dy fit­ted. This saves instal­la­ti­on time and at the same time ensu­res an opti­mal cur­rent flow wit­hout losses.

Clas­si­fi­ca­ti­on B2ca inclu­des the pri­ma­ry requi­re­ments of the cable for char­ging stations:

1. the con­tain­ment of the spread of flame
2. the limi­ta­ti­on of fire development
3. the limi­ta­ti­on of the rate of heat release.

Howe­ver, other cri­te­ria are essen­ti­al to pro­tect life and limb. Espe­ci­al­ly in the case of char­ging sta­ti­ons in under­ground gara­ges and par­king gara­ges, the cables must not pose any fur­ther dan­ger in the event of a fire. The­se addi­tio­nal clas­si­fi­ca­ti­ons are indi­ca­ted by the let­ters “s” for smo­ke, “d” for drip­ping and “a” for corrosive.

The addi­tio­nal clas­si­fi­ca­ti­on s1 d0 a1 is the hig­hest pos­si­ble clas­si­fi­ca­ti­on and includes:

s1: no strong smo­ke development
d0: no bur­ning droplets
a1: no cor­ro­si­ve gas evolution

If no addi­tio­nal clas­si­fi­ca­ti­on is given, the cable does not meet the­se safe­ty requirements.
