Independent Power Engineering Consultants
(IPEC) will be exhibiting an enhanced
version of the UltraSense cable insulation
monitor. This 16 channel monitor is unique
in providing 100% coverage of the critical
interface between the inner semi-conductor
layer and the insulation of HV and EHV
polymer insulated power cable.
These measurements bring early information
for process engineers and operators of the key
dimensional parameters of the cross-linked
cable, as well as generating a comprehensive
quality record for each reel of production.
The UltraSense monitor has been designed for
cables between 100kV and 750kV with an OD
between 50mm and 160mm. The equipment
provides accurate measurements of all three
wall thicknesses at 16 points around the
cable as well as providing true eccentricity
and ovality measurements for the cable as a
whole. A powerful feature of the system is
the ability to detect and alarm on thinning or
missing layers. Alarms can be set for voids and
inclusions in the insulation as well as fall-ins
and protrusions of the semi-conductor layers.
All this data is logged at preset intervals along
the length of a cable run. The operator or
process engineer can make an off-line analysis
either during production or after production
is completed. The data analysis software has
a powerful zoom facility that enables the
inspection of the cable structure millimetre
by millimetre in order to fault-find during
production process or in the event of a partial
discharge failure in post-production test.

Isolmax specialises in the manufacture of
thermoplastic materials and fibreglass. It has
worked for customers using Teflon, nylon,
lexan, PVC, glass epoxy, polyester glass and
many other materials.
The company is used to working to a high
quality on more complicated projects,
particularly for wire drawing machines (for
copper), producing flanges for coils and plates
for the annealing furnaces in thermosetting
materials. Fibreglass is a much better material
because of its durability, performance, cost,
heat resistance and dielectric strength.
The company also produces other
components in fibreglass and thermoplastic
material for other applications like driving
chains, tubes, pulleys, plates, bushes and
pipes etc.
