TE Connectivity (TE), has introduced its BATTU heat shrink tubing, a dual-wall, fire retardant product intended for battery/power cable to terminal applications in industrial and commercial vehicles, construction equipment, generator sets and more. The BATTU tubing products’ polyolefin jacket and thermoplastic inner adhesive wall provide excellent performance in harsh environments. With an approximate 2:1 shrink ratio, this tubing is tailored for power cable to terminal applications, allowing faster application and potentially reducing applied costs.
“Harness makers and OEMs asked us to help lower the applied cost for heat shrink tubing used over the cable to terminal interface on battery cables and other power cables, while still providing protection in harsh environments,” said Jing Lu, TE Connectivity’s tubing senior product manager. “Our team carefully evaluated the requirements and developed BATTU tubing. We optimized its composition, shrink ratio, sizes and cut lengths for faster application, while offering excellent electrical isolation, mechanical protection, flame retardance and moisture resistance.”
TE’s BATTU tubing product line comprises three sizes from 12.7 to 25.4 mm (unrecovered inside diameter) to accommodate typical cable sizes from 16-120 mm2 [6 AWG to 4/0 AWG]. Relatively short cut lengths, 32 to 102 mm, are tailored to expected application requirements, with specific lengths offered by tubing size. Additionally, 1.22 m long sticks are available.
Full recovery temperature is 135°C, and BATTU tubing can be used in operating temperatures from -40 to 130°C. This new tubing is flame retardant per IS07622 and is UL recognized, file E85381. Its voltage rating is 600 V, and its dielectric strength is 19,700V/mm, minimum.
BATTU tubing’s jacket offers protection from abrasion and bending, while withstanding exposure to many common automotive fluids. Its adhesive liner can bond to a variety of substrate materials, including plastics, metals and rubbers, and it provides protection from moisture ingress.
To aid in color coding connections, BATTU heat shrink tubing is offered in four standard colors – black, red, yellow and orange.
The tubing can be easily installed using many different types of heating tools, ranging from basic heat guns to conveyor-equipped ovens, for high-volume production environments.
