🛡 Technical Support: LSZH Jacketed Flexible Conduit FAQ

Q1: What does LSZH stand for, and why is it critical for public infrastructure?

LSZH stands for Low Smoke Zero Halogen. In the event of a fire, this specialized jacket emits extremely low levels of smoke and zero toxic halogen gases (such as chlorine or fluorine). It prevents smoke blindness during evacuations and eliminates acid gas formation that can destroy electronic equipment, making it a mandatory standard for subways, tunnels, and airports.

Q2: What is the flame retardancy rating of the AS-PAG13PLSZH series?

The LSZH jacket compound used in Kaiflex conduits is highly flame-retardant and self-extinguishing. It limits the spread of fire along cable runs and conforms to stringent international fire safety standards required in mass transit applications.

Q3: Does this LSZH metal conduit provide waterproof protection?

Yes. While prioritizing fire safety, the LSZH jacket is extruded tightly over the steel core, providing full liquid-tight protection. When combined with our matching heavy-duty connectors, the assembly achieves an IP64 rating, sealing out moisture, dust, and condensation.

Q4: What are the mechanical strength properties of the underlying Square-lock structure?

Beneath the LSZH jacket lies a precision-formed, hot-dipped galvanized steel core featuring a Square-lock profile. This design provides high crushing resistance and solid mechanical shielding against physical impacts, while maintaining excellent bend flexibility for complex routing.

Q5: Can Kaiflex supply custom certificates and specific dimensions for government tenders?

Absolutely. As a major direct manufacturer in China, we regularly support global infrastructure tenders. We can provide standard trade sizes (from 1/2" to 2" or metric sizes) and supply the necessary technical documentation, test reports, and custom reel packagings required for your project approval.
