    System Architecture & Testing Workflow of NH-016 Fire Resistance Test Machine<\/h3>\n

    Standardized Testing Workflow:<\/strong><\/p>\n

      \n
    1. Mount the sample cable onto the stainless steel ladder support and secure it using the 150mm metal rings.<\/li>\n
    2. Connect the cable conductors to the 5-circuit electrical transformer load system and set the target test voltage (up to 1000V).<\/li>\n
    3. Position the mobile ribbon burner at the specified distance (40\u201360 mm horizontally, 100\u2013120 mm vertically) from the specimen.<\/li>\n
    4. Select the flame protocol (e.g., BS 6387 Protocol C at 950\u00b0C) and initiate high-voltage electronic spark ignition.<\/li>\n
    5. The PLC tracks real-time current and temperature; if a conductor short-circuits or breaks circuit integrity, the system logs the failure time and triggers safety shut-off.<\/li>\n<\/ol>\n

      Target Customer Applications:<\/strong><\/p>\n

        \n
      • Fire-resistant power cable, communication line, and optical fiber cable manufacturers.<\/li>\n

        NH-016 Cable Fire Resistance Test Machine FAQ<\/h3>\n

        Q1: What is the main difference between BS 6387 Protocol C and IEC 60331 tests?<\/h4>\n

        A:<\/strong> BS 6387 Protocol C subjects the cable to a higher flame temperature of 950\u00b0C \u00b1 40\u00b0C using a 610mm ribbon burner for 180 minutes, whereas standard IEC 60331-21 tests typically apply a 750\u00b0C to 830\u00b0C flame. The NH-016 includes specialized burners to perform both tests seamlessly.<\/p>\n

        Q2: How does the system handle cable short-circuit events during high-voltage loading?<\/h4>\n

        A:<\/strong> Each of the 5 testing circuits is equipped with an independent fuse (2A) and circuit protection. When a cable insulation fails and causes a short-circuit, the system immediately cuts power to the affected channel, sounds an audible alarm, and records the exact time of breakdown.<\/p>\n

        Q3: Is the chamber suitable for water spray and mechanical shock testing?<\/h4>\n

        A:<\/strong> Yes. The heavy-duty 304 stainless steel rack and chamber structure are engineered with high load capacity and drainage considerations, accommodating auxiliary water spray nozzles and mechanical shock impact hammers required by BS 6387 Protocols W & Z and BS 8491.<\/p>","protected":false},"excerpt":{"rendered":"
