Bulk H07RN-F Flame Retardant Rubber Cable with Temperature Range -25°C to +60°C

Stranded bare copper class 5 conductors give this cable a flexibility you wouldn't expect from something 450/750V, and the synthetic rubber jacket handles temperatures form -25°C to +60°C without stiffening up too much — it's pretty much standard for rough-site work.

Rated up to 4mm² cross-section with 1 to 5 cores, you'll see a testing voltge of 2500V on the spec sheet, and the minimum bending radius is 15 times the outer diameter (which means you can pull it tighter than most rubber cables without damaging the insulation, actually).

We usually have stock in 1.5mm², 2.5mm², and 4mm² sizes, but the 2.5mm² 3-core is what most buyers go with for construction site power distribution. It's not ideal for fixed indoor installations where PVC is cheaper, but for outdoor or underground runs where you need flame retardant properties, this is the one.

It carries ISO9001, CE, and CCC certifications, and we include a COA with every coil (usually HPLC-tested for conductor resistnce, though I'd double-check teh exact spec table if you need a specific tolerance). One thing you might not think to ask: the sheath marking is legible even after a few months of dragging over concrete — that matters when inspectors come around.

Lead time is typically 10-15 working days for standard sections, but if you need something outside the 1.5mm² to 4mm² range (like 6mm² or 10mm²), we can get it in about 3 weeks or so — just confirm before ordering because those aren't always on the shelf.
