UL/CSA ratedmoisture curable EPR compounds ▲ ▲ The new compound from Electric Cable Compounds

for cable types XHH, XHHW, XHHW-2, RHH, RHW, RHW-2 and SIS as well as CSA 22.2 No. 38-05 for RW-75, RWU-75, R-90 and RW-90. Also available is AquaGraft 16-5150, which is designed for use in UL/CSA 150°C rated AWM and SAE J1127 cable applications. Cables are able to pass FT-2 Flame Rating and UL Horizontal Flame tests, and trials are now underway on VW-1 rated materials. New systems are actively being developed and customer-specific requirements can be accommodated. Electric Cable Compounds Inc – USA Website : www.electriccablecompounds.com

control cables, submersible pump cables, mining, power, and other specifications requiring superior thermal, mechanical, and electrical properties. The AquaGraft products are composed of a multi-component system that will yield a finished compound to allow the cable to pass various industry-recognised flame tests and comply with numerous industry-recognised requirements. Being able to offer a UL/CSA approved product allows AquaGraft to be differentiated in its ease of customer use qualification and speed to market. Industry approvals have been obtained for AquaGraft 16-100 which is UL 44 listed

Electric has introduced its new AquaGraft line of moisture curable EPR compounds allowing cable manufacturers to produce flexible rubber cables on standard thermoplastic lines without the need of a CV line. AquaGraft’s design allows for superior storage shelf-life prior to use, while after extrusion cables quickly cure with exposure to environmental moisture at ambient temperature over time or at accelerated rates with exposure to sauna or hot water after extrusion. AquaGraft compounds are designed for use in various low/medium voltage applications including building wire, Cable Compounds

Precision flat wire for industrial applications

Depending on the required applications, such flat wire can be delivered with different edge shapes. Natural rolled edges represent an economical solution in mid-latitude thickness ratios. Rounded edges, ie edges that go through a peeling process after cold rolling, offer an even closer and more regular

Cold-rolled flat wire nowadays plays an important role for industrial components such as closing and locking systems, safety devices, control elements, wiper blades and electrical connectors, thanks to its wide range of applications. Properly defined by material, dimensions and tolerances as well as mechanical properties, flat wire can be used in almost every industry sector.

tolerance in width, especially for high quality products with very tight bending radii. Rolled edges are formed by a vertical pair of rollers, allowing similarly chased edges and narrower tolerances in width. For such applications, stainless-steel flat wire is commonly used – both traditional materials, such as AISI 300 and 400 series, and special alloys. In general all cold-formable materials can be supplied as flat wire, for which procurement is possible.

Following the trend toward highly automated manufacturing processes, tight dimensional tolerances are often required, whether in the automotive sector, in precision engineering or medical technology, textile machinery or even for electrical connectors.

Flat wire from Studer-Biennaform is available in industrial quantities from widths of about 0.2mm (0.007") and thicknesses from about 0.05mm (0.0002"). Tolerances in width of ±0.005mm (0.0002") and ±0.001mm (0.00004") in thickness are achievable considering width-thickness ratios of up to 70:1. Compared to steel strip, cold-rolled flat wire has the advantage of very large core lengths without welds (up to 40km per spool and more), and a homogeneous distribution of the strength over the entire cross-section.

Thanks to a stable supply-chain, supported by a broad set of machines for cold rolling,

heat treatment and surface treatment, small quantities for validation purposes can be assured as well as large annual contracts with partial deliveries and accurately maintained tolerances.
