Can you check an equivalent cable from another manufacturer?

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.

What if the required size, core count or construction is not shown on the website?

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.

Can LV and MV cables be supplied in the drum lengths shown in our cable schedule?

Requested drum lengths can be reviewed with the cable schedule. What is practical depends on cable dimensions and weight, total quantity, drum capacity and transport or site-handling limits, so the required lengths should be included with the enquiry.

Is there one MOQ for all HORNOUR cable products?

No single MOQ applies across the entire range. The practical quantity depends on the cable type, size, construction, packing and production conditions. Send the actual cable list and quantities and we can confirm the applicable requirement for those items.
