FAQ

Questions engineers ask first

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

What does 'OF' mean in A-2YOF(L)2YB2Y?
'OF' stands for petrolatum jelly core filling (Öl-/Petrolat-Füllung). Unlike air-spaced cables where water entering a jacket puncture can wick tens of metres along the core interstices, the hydrophobic petrolatum compound fills every void between the star-quads for permanent longitudinal water blocking.
How do 'OF' and '(L)2Y' work together against groundwater?
The '(L)2Y' copolymer-coated aluminum tape fused to the inner PE sheath blocks radial water-vapour permeation through the jacket wall, while the 'OF' petrolatum filling prevents longitudinal water propagation if the cable is mechanically damaged.
Does petrolatum jelly filling increase the cable's mutual capacitance?
Because petrolatum jelly has a permittivity (εr ≈ 2.2) higher than air (εr = 1.0), the 2Y polyethylene core insulation wall thickness or cellular-skin structure is proportioned so mutual capacitance remains ≤ 50–55 nF/km at 800 Hz.
What is the difference between St III (n×2) and St I (n×4) versions?
Both use 4-wire star-quad twisting; in subscriber telecom notation (St III), a 20-pair cable is designated 20×2 (10 star-quads), whereas railway and trunk cables (St I) state the quad count directly as n×4 (e.g., 10×4×0.9 mm).
