INDEXTeknor Apex Europe manufactures
compounds in four broad product families
based on these widely differing TPE
chemistries: styrenics – blends of styrene block
copolymer rubber and thermoplastics;
vulcanizates – compounds consisting
of cross-linked elastomers within a
thermoplastic matrix; olefinics – blends
of polypropylene or polyethylene with
thermoset rubber or with olefin block
copolymer (OBC); and over-molding
compounds – proprietary blends that can
bond to a wide range of styrenic and
engineering resins.
New alloys for rod
RUSAL, one of the world’s largest aluminum
producers has announced that its rare
earth and transition metals aluminum
alloys for wire rod for the cable industry have
entered production.
The technology to enable the production
of cable alloys based on aluminum with an
increased resistance to temperature and,
as a result, with higher power transmission
capacity, was developed jointly with
scientists from Siberian Federal University,
Ufa State Aviation Technical University and
the Chemistry Faculty of Moscow State
University. The initial trials were carried out
at Tomsk cable plant.
A multifunctional casting, rolling and pressing
facility is currently being installed at Irkutsk
aluminum smelter. It will be capable of
producing 2,200 tonnes of wire rod per
month, from aluminum alloys with rare
earth and transition metals. The product is
already in demand by the cable industry.
“Cables made from the new wire rod have
much better characteristics. Their durability
and resistance to temperature is about 50
percent higher than normal ones have. Re-
garding the significant deterioration of the
Russian power grids, new cables will benefit
not only metals and cables producers, but
also grid and power companies. RUSAL’s
product is also significantly cheaper than
its US or European counterparts. We ex-
pect this product will be able to partially
supersede the expensive copper cables
and broaden aluminum application limits,”
commented UC RUSAL’s technical director,
Viktor Mann.
Cable entry seals
RoxtecBG™solutions combine the simplicity
and flexibility of the Roxtec multi-cable
transit sealing system with the ability to
bond and ground metal clad or armored
cables. The new system provides protection
against weather, explosion, and rodents
and is fire-rated for bulkheads, walls, decks
and floor entries.
As with other Roxtec cable seals, Roxtec BG
(bonding and grounding) can be used in
many different industries. “Roxtec BG was
an instant success within onshore oil and
gas, for which it was originally developed.
Then it was discovered by our telecom
customers. We now experience a huge
interest in this electrical safety solution
also from customers working with offshore
projects all over the world,” says Fredrik
Timonen, global segment manager oil and
gas offshore, Roxtec.
Roxtec BG solutions are designed to
increase the cable density capacity while
decreasing the footprint. They are up to
70 percent more area efficient than
traditional cable glands. A single ‘window’
cut-out in a cabinet can accommodate
up to 32 cables, replacing 32 individual
knock-outs and 32 cable glands. It allows
installers to use smaller, lighter cabinets and
reduce costs.
Tow cable
UK cable manufacturer Elmeridge Cables
has announced the availability of its new
Elmtronic range of tow cables, produced
using a highly specialized steel wire. The
range is designed to provide exceptional
yield strength and a high degree of corro-
sion resistance, while remaining non-mag-
netic at sub-zero temperatures.
The cable carries 2 x 50 ohm coaxials +
2 x 6mm
2
conductors + 4 pairs of 24AWG
with aluminum foil screen, and 3 layers of
torque-balanced, contra-helical, special
steel wire armor with 38-ton breaking strain.
This austenitic stainless steel has corrosion
resistance greater than that provided
by types 316, 316L, 317 and 317L, plus
approximately twice the yield strength at
room temperatures. In addition, the steel
has excellent mechanical properties at
both elevated and sub-zero temperatures.
Unlike many austenitic stainless steels it does
not become magnetic when cold worked,
and it has a yield strength about three to
four times that of type 316 stainless steel.
Optical monitoring
Lanode has released of a range
of manufacturer independent optical
monitoring equipment that expands the
organization’s security products portfolio.
