Shortening High-Voltage Cables - Simco-Ion MEB Notice D'utilisation

5.3. Shortening high-voltage cables

Warning:
- The electrical installation must be carried out by an electrical engineer with the
relevant training and qualifications
- Disconnect the power supply before carrying out work on the unit
Ionisation equipment high-voltage cables may be shortened. The metal shielding must not be
shortened by the customer. Shielded coax cables must be finished as shown in figure 3.
Please note: The sizes to be used with an MPM are indicated by @MPM.
For the blue high-voltage cables, the cable end must be finished as shown in figure 4.
The high-voltage cables of type SS anti-static bars can be stripped in the usual way.
Note:
 Do not damage the layers of insulation underneath!
 When you are stripping high-voltage cables, do not bend them by a radius sharper
than 45 mm. Sharper bends will shorten the service life of the cable!
Figure 2: Stripping the cable sheath
General instructions for stripping the cable sheath correctly:
- You should ideally use a specialised cable knife or another sharp knife to strip the cable
- Avoid bending cables sharply while you are finishing them
A Score around the sheath to mark the desired length, without touching or damaging the
shielding or the layer underneath.
B Score the sheath along this length, without touching or damaging the shielding or the layer
underneath.
C To remove the sheath, pull it apart up to the cut around its circumference and then pull off the
exterior sheath.
