Features

High Temperature Resistance: Can work stably at 90°C, suitable for wiring needs in high temperature environments.

Safety: Suitable for use in areas with fumes and toxic gases, emphasizing its suitability in places where public safety is important.

Internal Wiring: Designed for use inside equipment or in conduits, indicating its suitability for installation in delicate or restricted spaces.

Material Adaptability: Typically utilizes high quality insulating materials such as PVC or rubber to ensure electrical performance and mechanical protection.

Technical Characteristics

Application Scenario

Industry & Construction: Due to its high temperature resistance and safety features, H07Z-R cable is commonly used in industrial equipment, internal wiring of switchboards, and electrical installations in buildings.

Public places: suitable for installation in government buildings, hospitals, schools, etc., where there are strict requirements for electrical safety and smoke toxicity.

Equipment in high-temperature environments: such as heating systems, dryers, etc. Wiring inside or around such equipment requires cables that can withstand high

temperatures without compromising performance.

Inside electrical equipment: Wiring inside electrical equipment that requires high reliability and durability to ensure long-term stable operation of the equipment.

In summary, H07Z-R power cables are widely used in electrical installations and inside equipment that require high safety standards and can withstand

extreme temperatures due to their high temperature resistance, safety and reliability.
