AFR-250 Series PTFE Film Wrapped Insulated Hookup Wire

AFR-250 Series PTFE Film Wrapped Insulated Mounting Wire Hookup wire

It is mainly used in the aerospace field and ground test system connection, and other military field ground equipment electrical connection.

Q/WHY 61.3-2019 The specification of AFR-250 Series PTFE Film Wrapped Insulated Hookup Wire for Aerospace & Aviation

Rated voltage:250V, industrial frequency AC.
Rated working temperature: 250℃.
Minimum working ambient temperature: -65℃ for wire, -55℃ for cable;.
Minimum bending radius: 5 times the outer diameter of the wire, 8 times the outer diameter of the cable.
Bare shielded products are not allowed to work for a long time under salt spray environment.

● Low temperature winding
After -65℃, 4h low temperature winding test, the insulation should not be cracked, water immersion withstand voltage 1.5kV, Imin test should not be broken.
Cable by -55 ℃, 4h of low temperature winding test, protection should not crack, diffuse water withstand electric music test 1.0V, 1min should not breakdown.
● Temperature outside the strike
Wire by (260 +2) ℃ x 30min, (-55 +3) ℃ x 30min for I cycle, a total of 4 cycles of temperature shock test, no crack, no flared open, insulation shrinkage ‘2.3lmm.
●Shrinkage of insulation
The wire is stored at a temperature of (290+2)℃, and the amount of insulation shrinkage is ≤0.76mm.
● Laminated sealing
Wire and cable by (200 + 2) ℃, 48h test, insulation and sheath layer should be no delamination or layer separation phenomenon.
● Moisture resistance
Wire after 15 cycles, a total of 360h moisture resistance test, the specimen is immersed in 5% chlorinated pin solution for 4h, after 500V insulation resistance test, resistance value > 100M a few, km.
● Enchanting wires and cables in the process of combustion test shall not have combustion abatement burning the napkin below the specimen. Test conditions for the fire time 30s, delayed combustion time S30s, delayed combustion length ≤ 76mmm.
The wire colour is white by default. Multi-core cables (maximum number of cores is 7), the insulation colour sequence is designed as white, blue, red, yellow, green, orange, brown.
Brown. The sheath colour is white by default if there is no special requirement.
