M27500 – MIL-SPEC WIRE & CABLE

M27500 – HIGH TEMPERATURE AIRCRAFT CABLE

GENERAL INFORMATION

According to the Defense Logistics Agency (DLA), MIL-DTL-27500 (M27500) has been superseded by the NEMA-WC27500

This popular specification covers high-performance of power electrical cable shielded or unshielded. Most of the aircraft manufacturers are using this standard due to the wide range of options.

Basically , you can easily build or customize your multicore ,single core shielded or unshielded cable.

Due to this multitude of choices you can find an alternate solution especially if you are having sourcing issue with your existing cable.

You can benefit from the performance of the AS22759 ( M22759) by using the WC-27500 symbol in the break down of the M27500.

In addition, a large choice of external jacket and shielded material is available where other standards offer only one material for the shielded and the external jacket.

These combined advantages are the perfect solution to meet your enginneer’s requirements.

Moreover, due to our high quality policy , Air Cost Control offers only QPL ( Qualifed Part list) cable according to the latest revision in order to support you on your project and daily business.

At Air Cost Control, we offer other different services such as : kitting,re-spooling,customized cable identifications and laser marking.
