Product Name:
BG5203 Wire and Cable Fire resistance Tester
AddDate: 2014-05-16
- Summary:
It’s used for testing fire resistance of the cable or optical cable to get and judge their refractability when in the flame conditions.
Applied to the standard GB/T19216(11-31)-2003, “in the flame conditions, the integrity test for the cable or optical cable line” and GB/T19216-12-2008 standard of “in the flame conditions, the integrity test for the cable or optical cable line, part 12, testing device, The flame temperature won’t be below 830℃ for the heat, and put some impact on”. Also applied to the IEC60331-1999; 2002 standard.
Standards:
GB/T19216 (11, 21, 23, 25)-2003
GB/T19216 (12, 31)-2008
IEC60331-23: 1999
IEC60331-12: 2002
Technial parameters:
◆ Burning holder: The combustion frame is a cabinet type, fire-resistant characteristics and fire-resistant impact. It is easy to operate and has a beautiful appearance.
◆ Burner: 500mm belt type blower (including venturi mixer), burner row 3 rows of staggered hole diameter: ￠ 1.32 center distance: ￠ 3.2, burner can be adjusted up and down, left and right to meet the horizontal and vertical distance of the cable Positioning
◆ Refractory characteristic bracket: consists of two metal ring brackets with an intermediate length of about 300 mm, an experimental support metal ring with an inner diameter of 150 mm and a ring cross-section diameter of 10 ± 2 mm. One end of the sample holder is fitted with a clamp to fix the sample, and the other end is convenient for heat testing. Vertical transfer
◆ Refractory impact bracket: The impact test ladder frame is composed of steel frame. In order to adapt to the test of different size cables, two vertical steel members located on the test ladder can be adjusted. The test ladder frame is about 1200mm long and about 600mm high. Test ladder The total mass is (18 ± 1) kg, the hardness of the four rubber bushing rubber bushings is (50-60) Shore A, and the impact bar diameter is (25 ± 0.1) mm long (600 ± 5) mm low. Carbon steel round composition, impact bar angle is 60°
◆ Sample application voltage: AC100V~1000V adjustable
◆ Sample short circuit breakdown current 2A
◆ Sample holding current 10-260MA adjustable
◆ Three-phase transformer: 380V, 9KVA
◆ The sample is short-circuited, the circuit is stopped, the fire is supplied, and the voltage is cut off. The software has a fault indication.
◆ Fire time: 0~999Min adjustable
◆ Two Ф1.5mm thermocouples for correcting flames and corresponding portable thermometers
◆ Control and regulation of gas source: air flow is adjustable for mass flow agent 20~100L/Min, propane flow is adjustable for mass flow agent 2~10L/Min.
◆ Control mode: controlled by computer software, monitoring current, voltage gas flow, test results, curve printing during test
