The ford sable parking brake cable is mainly used for transmitting low-voltage voltage or current signals and has wide applications in industrial and mining enterprises, energy and transportation departments, etc. So, what are the main technical indicators of the ford sable parking brake cable?

The main technical indicators of the ford sable parking brake cable include the following aspects:

I. Electrical Performance

Dc resistance: At 20℃, copper wires of different cross-sections have different DC resistance values. For example, the DC resistance of 0.4mm copper wire should be less than or equal to 148Ω/km, while that of 0.5mm copper wire should be less than or equal to 95Ω/km. This indicator reflects the electrical conductivity of the cable.

Insulation electrical strength: The conductors can withstand a voltage of 1kv within 1 minute without breakdown, and the conductors and the shielding can withstand a voltage of 3kv within 1 minute without breakdown. This indicator reflects the insulation performance of the cable.

Insulation resistance: When each core wire is grounded to the rest of the core wires, the insulation resistance of the control cable should be greater than 10,000 MΩ·km. This indicator is used to measure the resistance capacity of the insulation layer of the cable to the current.

Remote crosshabu defense degree: At 150kHZ, the average power of the specified combination should be greater than 69dB/km. This indicator reflects the cable's ability to resist external interference when transmitting signals.

Ii. Mechanical Properties

The long-term allowable operating temperature of the conductor: For control cables insulated with polyvinyl chloride, the long-term allowable operating temperature of the conductor is 70℃. This indicator determines the temperature limit of the cable in a continuous working state.

Cable laying temperature: The cable laying temperature should not be lower than 0℃. This indicator ensures that the cable will not be damaged due to excessively low temperatures during the laying process.

Allowable bending radius: For cables without armor layer, it should not be less than six times the outer diameter of the cable. Cables with armored or copper tape shielding structures should be no less than 12 times the outer diameter of the cable. The flexible cable with a shielding layer structure should be no less than six times the outer diameter of the cable. This indicator ensures that the cable will not be damaged due to excessive bending when bent.

Iii. Structural Features

The number of cores: Control cables have a relatively large number of cores. According to the standard, the maximum number is 61 cores, but they can also be produced according to the user's requirements. This feature enables the control cable to transmit more control signals.

Cross-section: The cross-section of control cables generally does not exceed 10 square millimeters, which matches its main function of transmitting control signals.

Insulation and sheath materials: Control cables are typically made of flexible, highly wear-resistant and tension-resistant insulation and sheath materials such as polyvinyl chloride to adapt to the environmental conditions they are frequently subjected to, including bending, stretching and mechanical pressure.

Iv. Other Performance Indicators

Working capacitance: The average value is usually 52±2nF/km, which reflects the capacitance characteristics of the cable when transmitting signals.

Flame retardant performance: Some control cables also need to meet flame retardant standards to ensure that they can still maintain certain performance in extreme situations such as fires.

The above are the main technical indicators of the ford sable parking brake cable. The main technical indicators of the ford sable parking brake cable cover multiple aspects such as electrical performance, mechanical performance, structural characteristics, and other performance indicators. These indicators jointly determine the transmission performance, service life and application scope of the cable.
