Wire fire resistance and spray testing instrument

Wire fire resistance and spray testing instrument

Wires and cables that are difficult to ignite and have the ability to prevent or delay flame propagation usually refer to wires and cables that can pass the GB/T18380.3 (equivalent to IEC60332-3) test; This wire fire resistance and spray tester is designed according to the standard BS6387. This equipment is used to test the flame retardant performance of the insulation layer of wires and cables under abnormal conditions such as overheating and overcurrent. It is a testing device used to test the standard current level in cables, and can also test the fire resistance and waterproof condition of cables.

Applicable scope:

This equipment is used to test the flame retardant performance of the insulation layer of wires and cables under abnormal conditions such as overheating and overcurrent. It is a testing device used to test the standard current level in cables, and can also test the fire resistance and waterproof condition of cables.

Reference standard:

BS 6387- Cable integrity testing under fire conditions - Appendix D.3 Performance requirements specification for cables that can ensure circuit operation under fire conditions

Product features:

Equipped with propane burner nozzle, burner opening of 36 × 5mm, combustion test temperature of 650 ± 4 ° C

The width of the front end of the burner is 15mm, the diameter of the small hole is 1.32mm, and the distance between the hole centers is 3.2mm. The combustion holes are arranged in three staggered rows

Equipped with a sun dryer, evenly sprinkled with water

Use thermocouples with a diameter not greater than ¥ 2 for temperature measurement.

Equipped with calibration bottles, the amount of water sprayed can be checked and controlled at any time

During the test, the test object should operate at the rated voltage and specified current, and an indicator light should be attached to reflect the test status.

The pressure range of the sprinkler is 250Kpa~350Kpa

The water spray rate is 0.25l/s/m2~0.30l/s/m2

No water supply system required, the bottom of the box comes with a water tank, which can maintain water circulation

There is an indicator diagram on the instrument to prevent improper water spraying from causing the flame to extinguish

Cover with protective power supply device to prevent short circuit

The burner can heat the temperature of the ignition source to 650+50 ° C

The voltage supply device has 3A or 2A fuses;

There are two operating modes: manual control by the control panel or automatic control by computer software. This is a customized design that users can choose from. If customized with IEC 60331-11,12 and BS 6387, users can use the Slidas system, and the cost will be correspondingly reduced

The testing box and sink are made of 304 stainless steel plates to prevent rust;

The water supply pressure of the sprinkler head is 12-14kg/cm, which meets the spraying needs;

The heat source is a stainless steel strip propane burner nozzle, equipped with Venturi mixer;

Burner combustion surface: 400 × 10mm, hole center distance: 3.2mm;

Mass flow controller (MFC) accurately controls propane and air flow rates;

Electromagnetic valve automatically controls the air source;

During the test, the test object should operate at the rated voltage and specified current, and an indicator light should be attached to reflect the test status.
