FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What does the 'BQ' designation mean in H05BQ-F?

In the CENELEC harmonised code, 'B' designates heat-resistant ethylene-propylene rubber (EI7 EPR) core insulation rated for +90 °C continuous conductor operation, and 'Q' designates a thermoplastic polyurethane (TMPU / PUR) outer sheath. Together they give a cable that won't melt on hot soldering irons inside and resists cuts, swarf and mineral oils outside.

When should I select H05BQ-F versus H07BQ-F?

Under EN 50525-2-21, conductor cross-sections of 0.75 mm² and 1.0 mm² are rated 300/500 V and designated H05BQ-F, whereas conductor cross-sections from 1.5 mm² upwards are rated 450/750 V and designated H07BQ-F. Both share the same EI7 EPR core insulation and TMPU polyurethane outer jacket.

How well does H05BQ-F perform in sub-zero cold environments?

Unlike PVC or chloroprene rubber cables that stiffen below −25 °C, the EI7 EPR core insulation and TMPU polyurethane jacket of H05BQ-F remain flexible down to −40 °C in dynamic motion and −50 °C in fixed installations, making it ideal for cold stores, winter construction sites and alpine machinery.

Is H05BQ-F halogen-free?

Yes. Both the EI7 cross-linked ethylene-propylene core insulation and the TMPU polyurethane outer sheath are free of halogens per IEC 60754-1, while also providing resistance to mineral oils (EN 60811-404), hydrolysis, microbes and UV sunlight.
