Features:
• Improved bow strength (no
holes)
• Wire is out of the airstream
• Bow shaped like a wing for
improved aerodynamics and
low cw factor
• Wear strip eliminated and
replaced by wear bushings
with windows for easy
inspection and dust cleaning
• Wear bushings can be
changed while bow is
mounted on the rotor
Advantages:
• Lower power (amps)
consumption and reduced
noise
• Higher TPM – maintaining
wire quality
• Reduced bow breakage
• Increased life on wear
surfaces reducing down-
times andmaintenance
• Wire breakds are contained
within the bow – extending
bow life

If the construction of the cable is two
layer, with an inner insulating layer and
an outer to provide the oil resistance,
the inner layer can be without flame
retardancy and SX554 is an ideal flexible
choice. If the construction requires
additional fire performance then SX-0612
is recommended, or SX559 for the
highest fire performance.

Long-term stability
It is almost one year since Anglia
Metal began manufacturing plain and
tin-plated copper wire in the UK for
export worldwide, and the company
continues to grow and is showing
long-term stability within the copper
market.
Anglia Metal supports a wide and
highly demanding range of industrial
sectors such as automotive, data, power,
defence, specialised cables and various
other applications using copper wire.
Quality requirements of these markets
are ever increasing and the company is
continuously developing systems and
improving its processes, flexibility and
knowledge.
As a BSI-approved company, quality is a
key factor to providing first class products
to its customers.
Anglia’s aim is to progress with its
continued excellence in customer service
and expand the business into other areas.

Leading SAFTM
technology
Technical Absorbents provides high levels
of innovation and product development
expertise to the global cable market
with its Super Absorbent Fibre (SAFTM)
technology.
The basic functionality of SAFTM is its
ability to absorb up to 200 times its own
weight in water, or 60 times its own
weight in saline, at an extremely fast
absorption rate. Being fibre-based, it can
be precisely tailored into a diverse range

of non-woven tape and yarn formats that
offer the potential for enhanced design
and performance.
SAFTM is already a key component for spun
yarns and non-woven tapes that provide
optimum protection for internal and
external cable applications. This dry active
system of water-blocking protection
for cable cores affords prevention of
water passage along the cable from a
joint or point of sheath damage. This is
achieved by a water-swellable yarn or
tape being placed within the cable during
manufacture.
In some instances, cables that suffer
damage can start to take on water. If a
SAFTM containing tape or yarn is in place,
this will rapidly absorb the liquid at the
point of entry and swell to form a gel,
blocking any further water ingress.
This ensures any damage is minimal,
fully contained and is easy to locate and
repair. This situation can occur in many
different cable types, including telecoms,
medium and high voltage, industrial and
underwater. Without such water-blocking
technology, the results of water ingress
into the cable can be costly and very
problematic.
There are three types of power
cables: low, medium and high
voltage. Water-blocking is generally
required only in medium and high
voltage cables that use cross linked
polyethylene (XLPE) insulation. In
copper cabling water can ingress into
the cable by diffusion through the outer
polyethylene sheath. This is a high risk
occurrence due to the fact that such
cabling is typically laid underground
in areas likely to be damp and wet. The
presence of water will degrade signal
strength due to capacitance changes.
Water-blocking protection of an
optical cable core is accomplished
by surrounding it with a dry
water-swellable tape and yarn that
will stop the entry and migration of
water should the cable’s outer jacket be
breached.
This protective measure is included
primarily to maintain the mechanical
integrity of the cable itself (eg prevent
ice crush from within the cable, fungus
growth, or corrosion of metallic
cable members when present). The
water-blocking protection is placed in
the buffer tubes with the optical fibre
during manufacture of the cable.
