FAQ

Questions engineers ask first

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

What does 'BB' stand for in H05BB-F?

In the CENELEC code, both the first 'B' (core insulation) and the second 'B' (outer sheath) denote cross-linked ethylene-propylene rubber (EPR, specifically compounds EI6 and EM6 per EN 50363). This all-EPR construction combines a +90 °C continuous conductor rating with dynamic cold flexibility down to −40 °C.

How does H05BB-F differ from H05BN4-F?

Both H05BB-F and H05BN4-F are rated 300/500 V and +90 °C under EN 50525-2-21 (HD 22.12). H05BB-F uses an EM6 EPR outer sheath that stays flexible down to −40 °C in motion and is naturally halogen-free, whereas H05BN4-F uses an EM7 chlorinated CSP sheath rated to −25 °C flexing that adds mineral oil and flame resistance.

Can H05BB-F be used in blast freezers and cold-storage rooms?

Yes. Because standard polychloroprene (EM2) and CSP (EM7) jackets stiffen below −25 °C, the EI6/EM6 ethylene-propylene elastomer system of H05BB-F (and H07BB-F for larger sizes) is specifically chosen for −40 °C dynamic flexing and −50 °C fixed wiring in cold stores and Nordic outdoor sites.

When should I choose H07BB-F instead of H05BB-F?

Select H05BB-F for light 300/500 V appliances and sensors using 0.75 mm² or 1.0 mm² conductors. For power circuits from 1.5 mm² up to 95 mm² or where a 450/750 V (0.6/1 kV fixed protected) heavy-duty sheath thickness is required, select H07BB-F.
