According to Texas A&M University researchers, the ants also are attracted to wire insulation
and can create electric shorts.
The thickness of the wire insulation
, corresponding to the minimum thermal resistance of heat transfer, is optimal.
This wire was routed in an area where chaffing of the protective wire insulation
was likely causing a short circuit, melting of the conductor and ignition of material in the instrument panel near the stereo.
Evaluation found oil pressure sensor wire insulation
chafed and grounding out.
Melt processable compounds based on Fluon fluoropolymer resins are suited for challenging uses, including wire insulation
, cable sheathing, tubing and molded parts.
Partial discharge occurs in voltage environments of 650 V or more, and leads to breakdown of the magnet wire insulation
. Therefore, the film thickness needs to be set to a thickness at which partial discharge does not occur.
Two connector design evolutions have occurred in the last year to make this possible: 1) the miniaturization of discrete wire insulation
displacement connectors and 2) poke home wire-to-board (WTB) terminations.
Additional features include a flexible, neoprene outer jacket with tamperproof stainless steel straps for resistance to moisture and corrosion, and an inner sleeve to provide a constant and smooth inner diameter in any position to facilitate wire pulling and prevent damage to wire insulation
At this time it was noticed that some motors failed when fed via an inverter and it was realised that the voltage spikes caused by the inverter could make micro holes in the enamelled wire insulation
. Many micro holes close to each other become one big hole and this is when the motor burns out.
The automaker is recalling the vehicle because the wire insulation
used in the heating unit is not up to standard, which could cause it to become exposed, increasingly the likelihood of a vehicle fire.
The headshed is working on a solution to stop these fires with added wire insulation
