➡ Go to Cold Shrink Terminations to view MV-HV cable terminations for 6.6kV, 11kV, 33kV and 66/132kV cables. Also – cable accessories including high-fault current rated cable glands, cable cleats and cable jointing tools for jointing and terminating of MV/HV power cables.

Cable Box Terminations & Connectors – Inner Cone & Outer Cone

Cold shrink is typically used for the dry termination of medium/high voltage 11kV-33kV cables into MV-HV air insulated cable boxes.

T&D also distribute MV-HV Connectors for terminating cable into metal-enclosed SF6 insulated medium voltage switchgears (GIS) and liquid immersed transformers.

BAND-IT ULTRA-LOK Alloy 625 Clamps

Secure Rubber Boot on TR-343 Transducer Elements

A key component of sonar systems for surface military vessels is the AN/SQS-53C Sonar array, made up of 576 TR-343 Transducers, the array is located in the “bulb” on the bow just below the water surface. Each of those transducers contains a rubber boot or sleeve secured with an ULTRA-LOK Alloy 625 band.

BAND-IT IDENTIFIED AS ONLY SOURCE

During the sourcing process, the US Navy identified BAND-IT as the only responsible source capable of providing the required supplies. Citing the potential for delays and unrecovered costs, the agency chose BAND-IT as the only approved manufacturer based on performance and testing requirements of the Critical Item Production Fabrication Specifications (CIPFS) for the Transducer.

TR-343 Transducer by the Numbers

• Current Quantity: 44,352
• 576 Identical Transducers make up the Sonar Transducer Array Unit 717
• Sonar Detecting Ranging Set AN/SQS-53C(V) 1&2 used on all Arleigh Burke DDG-51 Destroyers and several Ticonderoga CG-47 Class Cruisers

BAND-IT BAND-FAST

Precut BAND-FAST Clamps Delivers Performance & Value

In EJP Electric Submersible Pumping Systems

Epsindo Jaya Pratama (EJP) is a company that values quality.

If you visit EJP’s website, you will see a section that describes the standards they maintain for the pumping systems they produce, and the customer experience they promise. But like every business, they also are cost-conscious. The drive to cut costs for manufacturing their Electric Submersible Pumping (ESP) System compelled EJP to switch from BAND-IT fasteners to a competitor’s range of cable ties, a decision they soon reconsidered.

MONEY FLOWS WHEN OIL FLOWS

Subsea downhole oil extraction is different from convention drilling in the oil and gas industry because most of the energy required to transport the produced fluid is supplied by mechanical means rather than by reservoir pressure. That puts more “pressure” on ESP systems. Any time the system needs maintenance or repair, production is interrupted, and the well isn’t generating oil or revenue.

➡ BAND-FAST is part of a full line of products that have achieved the highest level of quality certification ISO 14001:2004 | ISO 9001:2008 | IATF 16949

BAND-IT BAND-FAST Stainless Steel Clamps

EJP’s customers expect their investment to pay off in reliability, and that expectation extends all the way down to the clamps. When EJP changed from BAND-IT to a cheap fastener made in China, the customer experience they delivered suffered – a direct result of the increased failure of the clamps.

Even though EJP had stopped using BAND-IT clamps, Fraser Ng, OEM/Project Manager for BAND-IT, maintained contact with them. “I had advised them of the high possibility that non-reputable companies in China may supply sub-standard quality . It really happened to them. The material they paid for did not meet their requirements.”

➡ BAND-FAST clamps can be secured with seals, clips, ear-lokt buckles or centre punch clips to meet all of your fastening needs.

3M Cold Shrink

Cold shrink tubing and moulded parts for electrical installation

Invented over 40 years ago by 3M, 3M Cold Shrink Technology is designed to make cable insulating, termination and abandonment as simple as possible. The secret of 3M Cold Shrink technology lies inside it, in the form of a plastic coil. After the 3M Cold Shrink Tube has been placed over the joint or cable end, this inner spiral is pulled out. The insulating tube then contracts and seals onto the cable, exerting constant radial pressure for the lifetime of the joint or termination.

3M Cold Shrink Tubes are installed easily and reliably without the use of cable jointing tools (e.g. gas torches or naked flames). The Cold Shrink tubes manufactured by 3M Electrical are made from extruded EPDM (Ethylene-Propylene-Diene-Monomer) or silicone rubber that are stretched onto a spiral core.

The benefits of cold shrink tubes clear a long-term environmental seal that has high performance even in extreme conditions.  The tool-free installation reduces downtime, installation time and training requirements.
