Embodiment 1

[0039] Example 1: Reference figure 1 and figure 2 , a vertical combustion test system used for flame retardant testing of special communication optical cables, comprising a box body 1, a control panel 11 located on the box body 1, a combustion chamber 12 arranged in the box body 1, and a The hanger 3 for hanging the optical cable 6. The hanger 3 is specifically a cross bar, on which a clip can be set or the optical fiber can be directly wound on the cross bar, and the flame gun 2 is arranged directly below the optical cable 6 in the combustion chamber 12, and the control panel 11 is used to control the flame gun 2 Spitfire. A baffle plate 13 is hinged on the casing 1, and the baffle plate 13 is positioned at the opening of the combustion chamber 12. The baffle plate 13 is provided with a through hole 14 and a transparent observation plate is arranged, and the observation plate is convenient for observing the situation inside the combustion chamber 12.

Embodiment 2

[0042] Embodiment 2, refer to Figure 4 , a vertical combustion test system used for flame retardant testing of special communication optical cables, the difference from Embodiment 1 is that the internal structure of the combustion chamber 12 is different from that of the flame lance 2.

[0043] refer to Figure 5 and Figure 6 , hanger 3 is arranged in combustion chamber 12, and hanger 3 comprises two hanging rods 31 that are horizontally arranged on the inner wall of combustion chamber 12, the first splint 32 that is fixedly arranged on a hanging rod 31, another hanging rod that slides is arranged 31 on the second clamping plate 33, the optical cable 6 is clamped between the first clamping plate 32 and the second clamping plate 33. The connecting sleeve 35 is welded on the second clamping plate 33, and the connecting sleeve 35 is slidably connected on the hanging rod 31. On the hanging rod 31, a spring 34 and a T-shaped adjusting sleeve 36 are sleeved. The adjusting sleeve...

Abstract

The invention discloses a vertical combustion test system for the flame retardance test of special communication optical cables, wherein the system is applied to the field of special communication optical cable tests. Therefore, technical problems of low artificial cable combustion test efficiency and high risk level are solved. The system comprises abox body, a control panel arranged on the box body, and a combustion chamber arranged in the box body. A scaleplate that is arranged vertically and is used for hanging an optical cable is arranged in the combustion chamber; and a flame gun for heating an optical cable is also arranged in the combustion chamber. The system has the following technical effect: the optical cable can be tested rapidly; and the personal safety of the tester can be protected.

Description

technical field [0001] The invention relates to the field of special communication optical cable testing, more specifically, it relates to a vertical burning test system for special communication optical cable flame retardant test. Background technique [0002] The special communication optical cable is composed of a cable core, a protective layer and an outer sheath composed of several optical fibers (generally ranging from several cores to thousands of cores). It is used at a specific wavelength, made of special materials and has special functions; the protective layer and The outer sheath is flame-retardant insulating rubber, and the vertical combustion method is a method for testing the flame-retardant ability of flame-retardant insulating rubber. [0003] The existing vertical burning method is to intercept a section of cable with a standard length, hang the cable vertically, heat the lower end of the wire with an open flame for a period of time, then turn off the open ...
