Cable FAQ

What do B2ca, Cca, Dca, and Eca cable ratings mean, and how do they apply to different installation environments?

These ratings indicate fire performance levels under the CPR standard. Higher ratings release less heat, smoke, and toxic gases during a fire, improving safety. Selection depends on installation location, local regulations, and project risk level.

How can I choose a CPR rating that balances compliance and cost-efficiency?

Confirm local building and fire regulations, then select the minimum rating that meets requirements. Hornour offers full B2ca–Eca options for safety and cost optimization.

When should I opt for a higher CPR-rated cable to maximize safety and value?

Use higher-rated cables (B2ca or Cca) in buildings with high occupancy, concentrated cable runs, or projects requiring elevated fire protection. Outdoor PV arrays typically perform well with Dca or Eca.

How do different climates affect CPR rating selection?

Selection should consider local climate, regulations, installation, and risk level:

Mild climates / rooftop PV: Eca or Dca

Building interiors / public buildings: Cca or B2ca

Hot and humid regions: Cca may be preferred

Large industrial/commercial: Cca or B2ca

How do high-rated CPR cables contribute to environmental sustainability?

They release less smoke and harmful gases in fire events. Hornour’s electron beam crosslinking reduces chemical additives, offering a greener production and use profile.

How can I confirm Hornour solar cables meet international standards?

Hornour cables comply with IEC 62930, EN 50618, UL 4703, EN 50525, CE/CPR (EN 50575), and RoHS, ensuring project compliance and smooth approvals.

How do Hornour cable materials and fire ratings reduce project risk?

Electron beam crosslinked XLPO insulation and sheath offer UV, high-temperature, and flame resistance, minimizing aging, cracking, and fire risks.a for internal wiring, Dca for standard construction, and Eca for outdoor rooftop PV systems.
