PRODUCT FAMILY · BUILDING WIRE · 450/750 V · CCC CERTIFIED
Building Wire — BV, BVR, RV, RVV
PVC-insulated copper building wire for fixed installations in residential, commercial and panel wiring. Our 60227 IEC range carries CCC certification (certificates 752 and 753), and the scope is printed honestly on this page: CCC covers the building-wire family, not power or medium-voltage cables.
§01 — Range
Building wire types — fixed, flexible, flame-retardant and low-smoke
PVC Building Wire (BV / BVR)
Solid (BV) and stranded (BVR) copper conductors for conduit, trunking and panels. The volume product of the family.
Flexible PVC Wire and Cord (RV / RVV)
Class 5 flexible single-core (RV) and sheathed flexible cord (RVV, 60227 IEC 52/53) for appliances and equipment feeds.
Twisted-Pair Signal Wire (RVS)
Twisted flexible pair for low-voltage signal and fire-alarm loops.
Flame-Retardant Building Wire (ZR-BV)
Flame-retardant building wire where the local code requires IEC 60332 performance.
Fire-Resistant Building Wire (NH-BV)
Fire-resistant building wire for circuits that must survive a fire — emergency lighting and alarm circuits.
LSZH Building Wire (WDZ-BYJ)
Low-smoke halogen-free building wire for hospitals, schools and public buildings.
CCC Certification Scope (60227 IEC series)
Certificate 2014010105747252 covers 60227 IEC 52/53 cords and RVS; certificate 2014010105747253 covers 60227 IEC 01/02/06 wires and BVR. Both valid to 2028-12-04. Scans are published on the product page and in the certificate library.
