NYCWY uses wave-laid concentric copper wires around PVC-insulated cores for engineered network and feeder connections.
NYCWY uses wave-laid copper wires with a counter-spiral copper tape around the insulated power cores. This forms an integrated outer conductor within the 0.6/1 kV cable construction for network and service applications that require that conductor function. The waveconal layer is therefore part of the specified electrical design rather than an accessory added after installation.
Keeping the power cores and waveconal outer conductor in one cable can reduce the need to coordinate separate parallel conductor runs. This is useful on repetitive service and network routes where installation space, support points and route management all have to remain consistent. The advantage comes from carrying the required conductor functions together through the same fixed route.
At each cable end, the wave-laid copper conductor has to be prepared and connected in accordance with the circuit design. Allowing for the outer-conductor cross-section, breakout length and available terminal space before installation prevents the termination from becoming an improvised site detail. This is especially important on repeated network connections where the same arrangement may be reproduced many times.
Designed for Public networks, Commercial distribution, Service feeders and Underground routes.

Yes. Send the exact cable designation and, where possible, the existing datasheet or project specification. We compare conductor material, construction, voltage rating, standards and the requirements that affect the installation before confirming whether an equivalent can be offered.
Send the exact requirement. The website does not represent every possible production combination. We will check whether the construction can be supplied and whether the required standards or certification scope also cover that version before it is quoted.
