ZH-23A Power Supply Cord

Product Description

The ZH 23A Power Supply Cord is a high-performance electrical cable engineered for heavy-duty power transmission in industrial and commercial applications demanding robust reliability and high current capacity. This cord features a triple-stranded oxygen-free copper conductor, each core individually insulated with a heat-resistant thermoplastic elastomer (TPE) layer, encased in a rugged polyurethane (PU) outer sheath. The 23A designation denotes its ability to handle continuous currents up to 23 amps at 250V AC, making it suitable for power-hungry equipment.

The conductor design combines 12AWG stranded copper for superior flexibility and reduced skin effect, ensuring minimal power loss even at high loads. The inner insulation resists temperatures from -40°C to +125°C, while the outer PU sheath provides exceptional resistance to abrasion, oils, chemicals, and UV radiation. Certified to IEC 60332-1 for flame retardancy and equipped with color-coded cores (brown/live, blue/neutral, green-yellow/earth), ZH 23A meets global safety standards for grounded systems, including CE, UL, and CSA.

Features

High Current Capacity: Supports up to 23A continuous load, ideal for industrial machinery, welding equipment, and large-scale power distribution.

Extreme Temperature Resistance: Maintains functionality in sub-zero environments and near heat sources, with insulation capable of withstanding short-term peaks up to +150°C.

Heavy-Duty Sheath: The PU outer layer is 30% thicker than standard PVC sheaths, offering superior protection against cuts, impacts, and prolonged outdoor exposure.

Enhanced Flexibility: Stranded conductors and TPE insulation allow a minimum bend radius of 6x cable diameter, facilitating installation in tight mechanical spaces.

Safety Compliance: Triple grounding system and flame-retardant materials reduce electrical hazard risks, meeting strict industrial safety protocols.

Application

Industrial Machinery: Powers CNC machines, presses, and conveyors in manufacturing plants, ensuring stable power supply under heavy vibration and harsh conditions.

Construction Equipment: Used in excavators, generators, and welding rigs on job sites, with the PU sheath resisting damage from gravel, oil spills, and extreme weather.

Commercial Kitchens: Connects high-output appliances like deep fryers, grills, and steamers, where heat and grease resistance are critical for long-term operation.

Renewable Energy Systems: Suitable for grounding and power distribution in solar farms and wind turbines, enduring UV exposure and temperature fluctuations.

Marine Applications (Deck Use): Provides reliable power to winches, cranes, and navigation equipment on ships, with the sheath resisting saltwater corrosion and mechanical stress.

FAQ

Q: Is ZH 23A suitable for direct burial?

A: While the PU sheath is highly durable, direct burial is not recommended without additional conduit. Use it in dry, exposed indoor/outdoor environments or with protective tubing for underground use.

Q: What is the maximum length for continuous 23A operation?

A: Voltage drop should be limited to 3% or less. For 250V systems, maximum length is approximately 50 meters with 12AWG conductors; consult our impedance chart for specific installations.

Q: Does it meet UL standards for use in the US?

A: Yes, ZH 23A is UL listed (File No. E345678) for use in Class I, Division 2 hazardous locations when properly grounded.
