45 Degree wire and cable combustion Tester
The 45° Cable Flame Test Apparatus is designed to evaluate the flame-retardant performance of low-voltage primary cables used in ground vehicle electrical systems. It is suitable for cables operating at DC 60 V (AC 25 V) or below.
The system consists of a control console, combustion chamber, burner, solenoid valves, high-voltage igniter, gas pipeline, and signal control wiring. With stable ignition, precise flame positioning, and automated test timing, the apparatus provides reliable and repeatable results for cable manufacturers, quality inspection agencies, and automotive laboratories.
Application
This instrument is mainly used for flame testing of automotive and transportation cables installed in low-voltage electrical systems. Typical testing applications include:
Automotive primary low-voltage cable flame spread evaluation
Verifies that ignition does not propagate excessively when the insulation is exposed to a small ignition source.
Quality control during cable production
Ensures each batch of cables maintains consistent flame-retardant performance.
Material verification for wire insulation and jacket compounds
Assists manufacturers in validating flame behavior of PVC, XLPE, and other insulation materials.
Vehicle electrical component safety validation
Helps automotive OEMs confirm cable compliance during system design and regulatory certification.
Standards Compliance
The apparatus meets the test requirements of:
GB/T 14820-2009 – High-voltage ignition cables for road vehicles
QC/T 730-2005 – Low-voltage insulated cables for automobiles
IEC 60695 – Fire hazard testing requirements

FAQ
1. What is the purpose of the 45° cable flame test?
It simulates the ignition conditions that may occur in automotive low-voltage wiring systems and evaluates whether the cable insulation can limit flame spread.
2. Which types of cables can be tested?
Low-voltage automotive primary wires, ignition wires, and insulated conductors rated at DC 60 V or AC 25 V and below.
3. What fuel should be used?
Methane or coal gas is recommended to meet the flame characteristics required by the standard.
4. Does the device support automatic timing?
Yes. Both flame application time and afterflame time are controlled and recorded automatically via the touch-screen interface.
5. Can I monitor the burning process?
The combustion chamber includes a transparent viewing window, allowing operators to observe the entire flame-spread behavior in real time.
