4.5. Description of the connecting devices
The connecting devices stand for a detachable connection between the drive unit and the
insulating hose. They consist of a female and a male coupling which can be engaged or
disengaged and present in the engaged state a pressure prove, leakage free connection.
4.6. Description of the cutting procedure
With cable cutter heads in the scissors style the two blades (Pos.-No. 12) move towards
each other on a circular path towards the cable.
The cutting head (Pos.-No. 11) must be positioned in an angle of 90° towards the cable in
order to avoid undesired shearing forces. The cable must be fed between the open cutting
blades.
In the slow working speed the blades penetrate the cable. The pressure pick-up happens as
described in the previous chapters.
5. Remarks in respect of the determined use
The portable cable cutting unit type ESSG serves to check cables whether they are live or
not
and
to cut stranded copper and Aluminum cables and conductors with a nominal
voltage of 60 kV and a nominal frequency of max. 60 Hz, respectively single core cables
up to 110 kV and max. 60 Hz, where it can not be determined whether they are live
without any risk for the operator. (see EN 50110-1 Abs. 6.2.3)
It is mandatory according to German law BGV A2 §6 Cl.2 that the line is made and
maintained inactive during maintenance. Do not disregard the safety instructions supplied
in the German standard DIN VDE 0105 part 100 Chapter 9.
Since determining a live state of a cables, especially earth cable, is not always possible
alternatively the live line status can be verified by cutting the cable with this safety cutting
unit. At the same time the net provider should be contacted.
5.1. Operation of the unit
1.
After removing the safety cutting unit out of the carrying case the unit must be checked
for possible damages.
2.
Roll out the insulated hose (Pos.-No. 9) completely. This distance serves for your safety
in case the cable should be live. Please take into consideration that the hose will get
shorter when under pressure. It must be guaranteed that the position of the cutting head
will not change during the cutting cycle.
Attention
When paying out the insulated hose please make sure that you can see the
section of the cable where the cable is cut.
This means provides that no trespassers stay in the danger zone. In addition and prior
starting the cutting procedure the cutting zone must be cordoned off in a 10 m radius.
In case the insulated hose can not be payed out due to a lack of space other suitable
means protection must be provided such as earth walls or ditches.
