FAQs‌

Q1: Can riser cables be used outdoors?‌

A: No, they’re designed for indoor vertical runs. Use outdoor-rated cables for exterior wiring.

Q2: What’s the max length for riser cables?‌

A: Typically 100m per reel, but custom lengths are available.

Q3: Are riser cables fireproof?‌

A: Yes, but only if labeled "flame-retardant" (e.g., UL 20296).

Q4: How to choose between copper and aluminum?‌

A: Copper offers better conductivity; aluminum is lighter and cheaper.

Q5: Can I splice riser cables?‌

A: Avoid splices in riser shafts—use continuous runs for safety.
