LFek-L
In the defense and aerospace industries, for permanent installation in onboard electrical systems with a voltage not exceeding 600 V, a frequency up to 1,600 Hz, and an operating temperature range for the conductors from -80 to 200 °C.
Key Parameters
- Constant operating temperature
- -80 °C to +200 °C.
- Rated voltage
- 600 V
- Test voltage for 50 Hz testing
- 3,500 V
Construction
- Vein
- Made of Cu-ETP1 electrolytic copper with a tin coating, in accordance with EN 13602.
- Insulation
- FEP-type thermoplastic fluoropolymer, available in all solid colors.
- Screen
- Shielded version (ek)
The conductor design complies with the PN-EN 60228 Class 5 standard.
It is possible to use CuSn or FeZn wires to create a braided reinforcement.
The „ek” designation refers to a shielded version. The optional braid, described as "armor," does not specify the material or coating of the shield.
Properties
Excellent resistance to harsh chemical environments.
Excellent resistance to moisture and UV radiation.
Exceptional resistance to fuels, oils, and lubricants.
Excellent mechanical strength.
Self-extinguishing and non-flammable, UL94-V0.
Standards
WT-4/MGW/09
