Application fit

Is A-2Y(L)2YB2Y H45 right for your machine?

Select A-2Y(L)2YB2Y H45 for railway axle-counter evaluators, FSK/DSL wayside modems, and ETCS interlocking circuits where standard 52–55 nF/km cables exceed line attenuation budgets.

Fixed installation

Suitable

H45 low capacitance (≤ 45 nF/km) extends unrepeatered transmission reach for audio-frequency and digital axle counters.

Immersion & wet locations

Suitable

Laminated '(L)2Y' Al/PE sheath blocks radial moisture while double steel tape armour ('B') resists rodents and ballast.

Energy chain / drag chain

Not suitable

Solid copper star-quads and double steel tape armour are designed exclusively for static burial and trough routing.

FAQ

Questions engineers ask first

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

What does 'H45' mean in A-2Y(L)2YB2Y H45?
'H45' specifies a maximum mutual operating capacitance of 45 nF/km at 800 Hz (compared with 50–55 nF/km in standard St I / St III telecom cables). Lower capacitance directly reduces high-frequency line attenuation (dB/km), allowing railway axle counters and SHDSL wayside links to span longer track sections without repeaters.
Why are wheel sensors and axle-counter evaluators sensitive to cable capacitance?
Modern railway axle counters transmit carrier-frequency FSK or digital signals between trackside wheel detection heads and interlocking evaluators. Excessive pair capacitance attenuates carrier amplitude and causes phase shift; H45 (≤ 45 nF/km) preserves signal margin over long block sections.
How does A-2Y(L)2YB2Y H45 differ from AJ-2Y(L)2YDB2Y H45?
Both feature H45 (≤ 45 nF/km) low-capacitance star-quads and double steel tape armour ('B'). AJ-2Y(L)2YDB2Y H45 adds a heavy copper wire screen ('D') beneath high-permeability steel tapes ('AJ-') to achieve a low reduction factor (r_k ≤ 0.1–0.3) against 16.7 Hz / 50 Hz AC catenary induction.
Can A-2Y(L)2YB2Y H45 be direct-buried in railway embankments?
Yes. Its '(L)2Y' aluminum-laminated PE inner sheath, double galvanised steel tape armour ('B'), and UV-stabilised HDPE outer sheath ('2Y') are rated for direct burial and concrete trackside troughs.
