Bunched Cable Vertical Flame Tester
The Bunched Cable Vertical Flame Tester is a laboratory testing instrument designed to evaluate the flame propagation performance and fire resistance characteristics of bundled wires and cables under controlled vertical burning conditions. The tester simulates cable fire exposure scenarios to assess flame spread, insulation performance, and combustion behavior. It is widely used by cable manufacturers, research laboratories, certification organizations, and quality control departments for product development, safety verification, and compliance testing according to international fire safety standards.
Application
(1) Electrical wire and cable manufacturers: testing flame propagation of bundled insulated copper or aluminum conductors.
(2) Power cable production: vertical flame testing of multi-core and single-core power cables.
(3) Optical fiber cable manufacturing: verifying flame resistance of fiber optic cables under vertical installation conditions.
(4) Quality control and R&D laboratories: flame retardancy evaluation, product certification, and material development.
(5) Compliance testing agencies: meeting international fire safety standards for cables.
(6) Electrical engineering and safety research: assessing drip behavior, flame spread, and combustion characteristics of different cable types.
