Introduction
This cable fire resistance testing equipment to be used for testing cables required to maintain circuit integrity when subject to fire alone or fire with shock where the test condition is based upon flame with a controlled heat output corresponding to a temperature of at least 750˚C or fire with shock at a temperature of at least 830 °C.
-
IEC 60331 Test for electric cables under fire conditions Circuit integrity
-
IEC 60331 Part 11 Fire alone at a flame temperature of at least 750˚C
-
IEC 60331 Part 21 Cables of rated voltage up to and including 0.6/1kV
-
IEC 60331 Part 12 Fire with shock at a flame temperature of at least 830˚C
-
IEC 60331 Part 31Fire with shock Cables of rated voltage up to and including 0.6/1kV
Control cabinet parameters:
- With double flow meters and pressure regulators.
- Automatic control of the testing process
- Intelligent detection function, when short circuit occurred in the sample during the test, automatic alarm and turn off the heat source
- Display: touch screen display temperature curve
- Timer: 0 to 9 hours 99 minutes 99 seconds
- Size of control cabinet: 650 (L)mm X400 (W)mm X1200 (H)mm
- Load: 0 ~ 600V test voltage is adjustable;
- Load current range: 0.1 ~ 3A, test current can be adjusted according to standard, but there is protection if above 3A ;
- The load capacity should be able to ensure that the test product can still be tested when the test current is close to 3A. It can also be applied to the load requirements of spray test and hammer test.
Fire Resistance:
- Heat source (Burner) requirements: 610mm (length) tubular gas burner.
- The test ladder frame for installing the cable is fastened on the supporting steel base; during the test, the vertical members on both sides of the test ladder can be adjusted according to different cable size requirements (test frame length: 1200mm, height: 60mm, total weight: 18±1kg)
- Inside diameter of metal ring is about: 150 mm.
- With a temperature measuring device (K type thermocouple with diameter less than 2mm,75mm away from flame jet).
- The front end of the burner is not less than 200mm from the bottom of the box, and the distance from the wall of the box is not less than 500mm
- According to the test class, the flame temperature is adjustable: 600 ~ 1000ºC
- The horizontal axis of the burner is 40-60MM away from the center of the test cable, and the vertical axis of the burner is 100-120MM away from the longitudinal axis of the sample cable
- Provide 5 metal rings with an inner diameter of approximately 150 mm as required by the standard. The distance between the metal rings can be adjusted freely, which is convenient for the test sample to be fixed and supported.
- Stainless steel sample tray, load 30kg
Mechanical shock:
1, Stainless steel bracket impact structure;
2, The hammer cone is a thick round steel bar with a diameter of 25mm and a length of 600mm..
3, The hammer cone is hammered in a free fall at an angle of 60°.
4, The motor drives the rod hammer for periodic hammering and impact action.
5, Strike cycle (time): 10~999S(can be set freely,standard require 30 ± 2S / time;)
6, Total test time: 0 ~ 9999S
7, The ribbon burner has a nozzle length of 500mm and a width of 15mm. There are three rows of staggered holes on the nozzle. The hole radius is 1.32 mm and the hole distance is 3.2 mm. Equipped with Venturi mixer.
8, Test temperature 600 ~ 1000 ºC can be set freely.
9, Thermocouple diameter is less than ¢ 2mm. (Shared with Fire Resistance part)
10, 0.25A current through each phase cable during the test.
Water spray:
- The ribbon burner has a nozzle length of 500mm and a width of 15mm. There are three rows of staggered holes on the nozzle. The hole radius is 1.32 mm and the hole distance is 3.2 mm. Equipped with Venturi mixer.
- Test temperature 600 ~ 1000ºC can be set freely.(Standard requires 650 ±40 ºC).
- Use a thermocouple with a diameter not greater than ¢2 to measure temperature.
- The water supply pressure of the spray head is 250~350Kpa, and the spray water amount to the sample is about 0.25~0.3L/m2/S.
- The sample to be tested should be a complete cable at least 1500 mm long, with approximately 100 mm of housing removed from each end.
- During the test, the test cable is energized through the isolation transformer and connected to the 3A fuse or circuit breaker, and there are on-off signal lights for each phase cable.
