JDR Cable Systems boasts in excess of 75 years
combined experience in the design and manufacture of
specialist, custom-built cable and umbilical systems,
frequently used in harsh, dynamic, subsea
environments.
JDR Cable Systems design and manufacture a wide
variety of strain cables and umbilicals for naval
applications as well as cables for tracking and
signature ranges. Most cable/umbilical systems
supplied for such applications are subjected to the
most physically demanding conditions in hostile
waters, their dynamic performance and reliability
crucial to efficient and economic operation. This most
demanding of applications poses a particularly stern
challenge to the cable designer/manufacturer.
STRAIN CABLES & UMBILICALS FOR NAVAL APPLICATIONS
JDR Cable Systems has an impressive track record in
the design and manufacture of rugged and innovative
marine cables. To meet customer applications and
specific requirements, the company draws upon a wide
variety of special materials and manufacturing
techniques.
SUBSEA CABLES, HOSES AND TERMINATIONS
JDR Cable Systems has the unique capability to produce
all cables, hoses, terminations and ancillary items
in-house, allowing changes in detail to be executed
without undue delay to critical schedules. The
company's European sites operate quality systems which
are fully approved to ISO 9001:1994. To ensure single
point responsibility, complete integrated packages can
be supplied, including fully terminated assemblies
incorporating electrical or optical connectors as well
as the mechanical strength required to transmit load
requirements through the cable. The company can also
provide handling winches, slip rings and rotary
unions, all factory outfitted and tested prior to
despatch. Our products and services include:
Terminations: cable and umbilical terminations to
support electrical, optical and mechanical connection
requirements. Custom designed, produced, terminated
and tested.
Sonar system cables: tow cables for ship and submarine
passive and active towed arrays. Helicopter dipping
sonar hoist cables.
Range cables: for fixed and transportable signature
ranges, tracking and surveillance systems and magnetic
and acoustic ranges.
Mine counter measure cables: tow and umbilical cables
for in-line combined influence systems. ROV and
Self-Propelled Variable Depth Sonar (SPVDS) tethers.
Consultancy services: specialist personnel with a
diversity of expertise and experience who are
available for engineering and project study work.
Offsite back-up services: engineers are available for
off-site support, testing and termination work.
Full range qualification testing: all the above
mentioned products can be subjected to customer
specified extensive qualification testing. Series
production is subject to customer approved Factory
Acceptance Testing.
CABLE TERMINATIONS
Our in-house termination facility is fully equipped to
design, manufacture and install a wide range of
terminations for all applications. These can
incorporate cable/fibre optic connectors, hose
fittings, mechanical terminals, Multi-connectors and
bend restrictors. Customers' own or specified
connectors can also be fitted.
In addition, JDR Cable Systems can supply complete
systems including cable handling systems,
electro/optical converters, connectors and jumper
harnesses.
SONAR SYSTEM CABLES
JDR Cable Systems' cables are designed to combine
maximum strength with minimum diameter and weight,
meet exacting electrical and data transmission
requirements and survive repeated duty cycles over a
long period without failure.
Strength members comprise aramid fibre braids/servings
or steel wire armour, torque balanced to guarantee
minimum rotation under load. Cable assemblies can
incorporate twisted pairs, coaxes, quads, optical
fibres and power cores, all custom-designed for
specific applications.
The company supplies neutrally buoyant cables for
submarine passive and active Towed Array Systems
(TAS), cables for surface ship passive and active TAS,
cables for target and decoy systems and SPVDS systems.
QUALIFICATION TESTING
All cables undergo stringent pressure and electrical
testing. In addition, sample lengths of cable or
umbilical can be subjected to a wide range of
mechanical, electrical and optical tests to ensure
conformance to pre-determined standards. These tests
may include ultimate tensile and/or cycle testing with
full component monitoring at the designed working
load.
Our purpose-built cycle/tensile test rig is capable of
in-line pulls to 100t and also of cycling umbilicals
up to 150mm in diameter at 50t whilst continuously
monitoring all components whether electrical, optical
or hydraulic.
