Import Flammability Test Equipment For Bundled Cables — Buy in wholesale FOB from Supplier in China

This flammability test equipment for bundled cables is designed to assess flame propagation resistance in vertically installed cable bundles under controlled conditions, as defined by GB/T 18380.31-2008. The test chamber measures 3200 mm in length, 2500 mm in width, and 4500 mm in height, with a sealed perimeter and an air inlet of 800 mm by 400 mm. The bottom of the chamber is elevated above ground level, and the steel ladder supporting the cable samples is positioned with its lowest transverse rung 400 mm from the floor. The sample's lower end is held approximately 100 mm above the floor, ensuring consistent ignition distance.

The equipment uses a propane gas burner with a flat metal flame plate containing 242 precisely drilled holes of 1.32 mm diameter, arranged in three rows with center spacing of 3.2 mm. Propane flow is adjustable between 2 and 20 L/min using a rotator flowmeter, while combustion air is supplied at 20 to 150 L/min via a regulated compressor. The burner is mounted on a trolley and positioned horizontally, with its flame center aligned between two ladder rungs and at least 500 mm from the bottom of the sample. Thermal insulation with a heat transfer coefficient of 0.7 W/m²K is applied to the rear and side walls to maintain stable internal conditions.

This equipment is commonly used by cable manufacturers, certification laboratories, and government inspection agencies for compliance testing of power, communication, and control cables. Buyers typically require the system to meet GB/T 18380.31-2008 or IEC 60332-3-24 standards. The unit operates on AC380V, 50Hz with a total power draw of 5 kW. Packaging is typically crate-based for freight, and lead time depends on configuration. Buyers should confirm whether calibration certificates and user manuals are included with delivery.

Zonsky Instrument Co, Ltd is based in Dongguan, Guangdong, operating from the Chuangfu Industrial Zone. The supplier is verified as a harbor-tier entity on the platform, indicating a history of transactional reliability. The listing does not disclose company size, years in operation, or client list. Response rate and average response time are not provided, suggesting limited buyer interaction history. The supplier's focus appears to be on manufacturing test equipment for cable and wire industries, with no indication of service offerings beyond equipment supply.

There is no mention of certifications such as ISO 9001, CE, or third-party lab accreditation in the source data. The supplier does not claim export experience, distribution networks, or after-sales support. The absence of these details implies the buyer must request them directly. The listing confirms only the technical design of the equipment and its alignment with GB/T 18380.31-2008. Buyers should not assume compliance with international standards unless confirmed in writing.
