Cables and accessories supplier Webb Industries, part of JSE-listed Jasco Group, now distributes US-based cabling product manufacturer Times Microwave Systems’ SilverLine range of coaxial cables in South Africa.
The range includes SilverLine test cables, the SilverLine low passive intermodulation (PIM) series, known as the SilverLine-LP series, and the SilverLine TuffGrip series.
The SilverLine test cables are cost-effective, durable and high-performance cable assemblies designed for use in a range of test and interconnect applications.
Webb Industries says the cables are manufactured from rugged, solid polytetrafluoroethylene dielectric cable with stainless steel connectors and a proven strain relief system.
This provides a long life and stability in applications where they are repeatedly flexed, mated and unmated.The
test cables are used in production, field and laboratory test environments and are economical enough to be used as interconnects in test systems.
Some of the more common application areas for SilverLine test cables include high-volume production test stations; research and development laboratories; environmental and temperature test chambers; as replacement for original-equipment manufacturer test port cables; field radio frequency testing; and cellular infrastructure site testing.
The main features and benefits of the SilverLine test cables include phase and loss stability; a long flex life; triple-shielded cabling; a high mating cycle; and stainless steel connectors.
The test cables also feature rugged, solder-clamp attachments and redundant, long-life strain relief systems.
SilverLine test cables are also available in a steel torque and crush-resistant armour option.
Further, the SilverLine-LP is the first test cable in the SilverLine range that is specifically designed for field and production PIM testing.
Webb reports that, unlike standard corrugated test leads that experience rapid failures as a result of kinking and connector-to-cable interface breakage, the SilverLine-LP is steel-armoured and has a solid metal back shell to protect the cable-to-connector interface against damage.
The robust design results in a longer product life and reduces the occurrence of faulty test results.
The company notes that the SilverLine PIM is suitable for use with portable PIM testers in field test applications and for use with benchtop PIM analysers in a lab or factory environment.
In the field, the test cable cuts costs by providing a more dependable test lead, eliminating the need to rebuild or reterminate a test lead on site, or cancel a test entirely.
In the factory, it saves labour by providing more accurate and consistent results over a far longer product life, reducing the possibility of rejects as a result of faulty test leads.
Other features include, greater than 117 dB per milliwatt performance, a set of low-PIM adaptors with optional connector saver and a retractable OneTurn connector for fast-on fast-off mating.
The test cable is much easier to handle than corrugated cable and is water-resistant and Restriction of Hazardous Substances compliant.
Meanwhile, the TuffGrip test cable, which is designed for sweep-testing cellular infrastructure site cables and antennas, has also been added to the SilverLine range of coaxial cables.
The TuffGrip’s features were designed by field technicians for field technicians and employ a large handgrip at the system-end to better withstand the rigours of fieldwork.
It meets the demands of repeated mating and unmating to cell-tower cables with connectors that may have degraded from exposure.
The robust handgrip allows the user to apply as much resistance as necessary to properly torque the system cable connector, while preventing excess torque from being applied to the test cable and enabling a proper connection to be made quickly with a single wrench.
TuffGrip test cables are double steel armoured and antitorquing, yet they are completely flexible.
All connectors are made of stainless steel, enabling thousands of mating cycles, while other features and benefits include permanently attached heavy-duty protective caps and a high-frequency operation to meet future needs.
