High Temperature Control Cable

Basic Models: KGG, KFF, etc. Insulation material: silicone rubber or fluoroplastic.

High Temperature Control Cable is a special-purpose cable for transmitting control and monitoring signals in elevated-temperature working environments. It uses high-purity oxygen-free copper as the conductor, with silicone rubber or fluoroplastic insulation and optional shielding and protective sheath structures. The multi-strand conductor provides flexibility for equipment wiring, while the insulation and sheath materials can be selected according to the operating temperature and surrounding conditions.

This construction is intended for applications where temperature resistance is an important part of cable selection. Typical applications include metallurgy, heat treatment, industrial furnaces, thermal processing equipment and other industrial control systems. The actual cable specification should be selected according to continuous temperature, peak temperature, electrical requirements, installation conditions and exposure to oil, moisture or corrosive media.

Material and Construction

1. High-purity oxygen-free copper conductor

The conductor is made of high-purity oxygen-free copper in a multi-strand flexible construction. Compared with a rigid solid conductor, the stranded structure is more suitable for routing around equipment and control cabinets. The available conductor cross-section is 0.5mm² to 10mm² according to the listed specification range.

2. Silicone rubber or fluoroplastic insulation

Silicone rubber and fluoroplastic provide temperature-resistant insulation options for different operating conditions. Material selection should consider the continuous working temperature, short-term temperature exposure, mechanical requirements and surrounding environment rather than temperature alone.

3. Optional shielding for control circuits

The cable can be equipped with copper wire braiding or copper tape wrapping when shielding is required. The specified shielding coverage rate is ≥80%. Shielding is particularly relevant where control or monitoring circuits are installed close to equipment that may generate electrical interference.

4. Multiple sheath material options

The outer sheath can use high-temperature-resistant low-smoke halogen-free flame-retardant PVC, silicone rubber, fluoroplastic or nitrile sheath compound. The available construction provides different combinations of temperature resistance and resistance to oil, acid, alkali and other industrial conditions.

Performance and Application Considerations

The working temperature of a control cable is determined by the complete cable construction, including conductor, insulation, sheath and installation conditions. For this reason, temperature grade, environmental exposure and electrical requirements should be confirmed together before selecting a specification.

1. Long-term and short-term temperature requirements

The available long-term operating temperature grades are 90℃, 180℃ and 200℃. Depending on the selected construction, short-term peak temperature can reach 250℃ to 280℃. Silicone rubber and FEP fluoroplastic versions can also resist temperatures down to -60℃. The selected grade should correspond to the actual temperature profile of the equipment.

2. Electrical performance for control and monitoring circuits

The oxygen-free copper conductor provides the required electrical path for control and monitoring signals, while insulation resistance and withstand voltage provide measurable electrical performance indicators. Where electromagnetic interference is a concern, copper braid or copper tape shielding can be specified.

3. Resistance to industrial working conditions

High-temperature areas may also contain oil, moisture, dust, acidic or alkaline substances. The sheath should therefore be selected according to the actual surrounding medium. Silicone rubber, fluoroplastic and nitrile sheath options can be considered for different combinations of temperature and environmental exposure.

4. Flexible installation around equipment

The multi-strand conductor construction supports flexible routing around industrial machinery, control cabinets and thermal equipment. Core quantity, conductor cross-section and overall cable construction should be matched to the available installation space and circuit requirements.

Typical Industrial Applications

This cable is used for control, monitoring and signal circuits in industrial environments where elevated temperatures affect cable selection. Typical applications include:

●Metallurgy and metal-processing equipment

●Heat-treatment lines and thermal processing equipment

●Industrial furnaces and heating systems

●High-temperature production machinery

●Industrial control cabinets and equipment connections

●Temperature monitoring and control circuits

●Equipment exposed to oil, moisture, dust or corrosive industrial media

Quality Control and Technical Verification

For industrial cable procurement, product verification should focus on measurable construction and electrical parameters. Key items include conductor material, conductor cross-section, core quantity, insulation material, sheath construction, rated voltage, insulation resistance, conductor resistance and withstand voltage.

Production inspection can include dimensional checks, conductor resistance testing, insulation resistance testing and power-frequency withstand voltage testing according to the applicable product specification. For engineering and export orders, technical documentation and test records can be confirmed according to the required specification and project conditions.

What Should Be Confirmed Before Ordering?
