Electric Cable Compounds has
introduced its new AquaGraft line of
moisture curable EPR compounds
allowing cable manufacturers to produce
flexible rubber cables on standard
thermoplastic lines without the need of a
CV line.
AquaGraft’s design allows for superior
storage shelf-life prior to use, while
after extrusion cables quickly cure with
exposure to environmental moisture at
ambient temperature over time or at
accelerated rates with exposure to sauna
or hot water after extrusion.
AquaGraft compounds are designed
for use in various low/medium voltage
applications including building wire,
control cables, submersible pump cables,
mining, power, and other specifications
requiring superior thermal, mechanical,
and electrical properties.
The AquaGraft products are composed
of a multi-component system that will
yield a finished compound to allow the
cable to pass various industry-recognised
flame tests and comply with numerous
industry-recognised requirements.
Being able to offer a UL/CSA approved
product allows AquaGraft to be
differentiated in its ease of customer use
qualification and speed to market.
Industry approvals have been obtained
for AquaGraft 16-100 which is UL 44 listed
for cable types XHH, XHHW, XHHW-2,
RHH, RHW, RHW-2 and SIS as well as CSA
22.2 No. 38-05 for RW-75, RWU-75, R-90
and RW-90.
Also available is AquaGraft 16-5150, which
is designed for use in UL/CSA 150°C rated
AWM and SAE J1127 cable applications.
Cables are able to pass FT-2 Flame Rating
and UL Horizontal Flame tests, and
trials are now underway on VW-1 rated
materials. New systems are actively
being developed and customer-specific
requirements can be accommodated.

Cold-rolled flat wire nowadays plays an important role for
industrial components such as closing and locking systems,
safety devices, control elements, wiper blades and electrical
connectors, thanks to its wide range of applications. Properly
defined by material, dimensions and tolerances as well as
mechanical properties, flat wire can be used
in almost every industry sector.
Following the trend toward highly automated
manufacturing processes, tight dimensional
tolerances are often required, whether in the
automotive sector, in precision engineering
or medical technology, textile machinery or
even for electrical connectors.
Flat wire from Studer-Biennaform is available
in industrial quantities from widths of
about 0.2mm (0.007") and thicknesses
from about 0.05mm (0.0002"). Tolerances
in width of ±0.005mm (0.0002") and
±0.001mm (0.00004") in thickness are achievable considering
width-thickness ratios of up to 70:1.
Compared to steel strip, cold-rolled flat wire has the advantage
of very large core lengths without welds (up to 40km per spool
and more), and a homogeneous distribution of the strength over
the entire cross-section.
Depending on the required applications, such flat wire can
be delivered with different edge shapes. Natural rolled edges
represent an economical solution in mid-latitude thickness
ratios. Rounded edges, ie edges that go through a peeling
process after cold rolling, offer an even closer and more regular
tolerance in width, especially for high quality
products with very tight bending radii.
Rolled edges are formed by a vertical pair of
rollers, allowing similarly chased edges and
narrower tolerances in width.
For such applications, stainless-steel flat
wire is commonly used – both traditional
materials, such as AISI 300 and 400
series, and special alloys. In general all
cold-formable materials can be supplied as
flat wire, for which procurement is possible.
Thanks to a stable supply-chain, supported
by a broad set of machines for cold rolling,
heat treatment and surface treatment, small quantities for
validation purposes can be assured as well as large annual
contracts with partial deliveries and accurately maintained
tolerances.
