New Camel waterblocking yarns from A&E
Inc provide cable producers valuable flexi-
bility to tailor yarn count and absorbency
characteristics to meet specific application
requirements. Specifically designed for filler
and binder applications, Camel water-
blocking yarn is based on super absorbent
fibre (SAF) technology, which provides the
ultimate in rapid absorbency. Camel
waterblocking yarn can reach 90% of its
maximum absorbency in slightly more than
five seconds with an average minimum
absorbency of 30-grams/gram.
This specialised yarn provides for clean and efficient pay-offs from several
package formats. With SAF technology, absorbency is built into the yarn.
This feature translates into more absorbent material being conveyed into the
cable without the powder buildup inherent with most SAP yarn products.
Dependent on yarn size, package lengths of over 122,000m are available.
Fine-count yarn options (down to 288-decitex/34.7 km/kg) offer cable
designers a new dimension in loose tube constructions and cable weight
savings.

Global changes drive advancements
in HV/EHV power delivery systems
The growth of the high voltage (HV) and extra high voltage (EHV) global power
cable segment remains very strong, driven by industrialisation and urbanisation in
developing markets, replacement or refurbishment of ageing power transmission
systems in mature markets, and the trend toward underground installation. Dow
Wire & Cable works closely with customers, end users, industry associations and
testing facilities to develop solutions that can support evolving infrastructures.
The materials portfolio offers mechanical strength, flexibility, electrical properties
and ageing stability, and continues to set HV/EHV industry standards worldwide
for cleanliness, consistency, reliability and overall quality.
Growth and expansion also are an ongoing part of the company’s focus.
Dow Wire & Cable is enlarging its global reach with new and updated
manufacturing and R&D facilities and by adding new and industry-experienced
technical service, R&D, marketing and sales personnel.
Dow Wire & Cable provides a complete solution of compounds required by cable
makers to manufacture, test and easily install HV/EHV cables. Super clean cross-
linked polyethylene (XLPE) insulation compounds are mandatory materials for
underground HV cable constructions. HFDJ-4201 S from Dow Wire & Cable
meets global testing standards including IEC 62067 for voltage greater than
150kV. Designed for use in HV/EHV power cable applications for transmission
and distribution systems, HFDB-0801 and HFDA-0587 BK S conductor shield
and bonded insulation shield compounds provide improved processing
characteristics and are designed to be compatible with current semi-conductive
extrusion processing equipment. New HDPE black jacket resin (DGDK-6800 BK
EXP4) offers excellent mechanical and physical properties and outstanding
processability. It provides very good ESCR values and meets IEC 60502-1,
AEIC-CS7-93, ICEA 720, DIN VDI 02676-620 and type DMP9 requirements for
global power cable jackets. DHDA-7708 semiconductive jacket permits easy
DC testing of the cable either on the reel or after installation.
