Cable Types (CYA, CYKY, ALUPY, HOTDRN)
Selection Tables, Typical Applications, Temperature Ratings
Industrial cables differ in conductor material, insulation, mechanical strength and temperature resistance. Selecting the correct cable type ensures safe operation, long service life and compliance with installation standards. This section provides a practical comparison of four common industrial cable types.
CYA Cables
CYA is a single-core copper conductor cable with PVC insulation. It is commonly used in control panels, switchboards and internal wiring where mechanical protection is provided by the installation environment.
Typical Applications
- Internal panel wiring
- Distribution boards
- Protective bonding
- Industrial control circuits
CYKY Cables
CYKY is a multi-core copper power cable with PVC insulation and PVC outer sheath. It is widely used in fixed installations, industrial buildings and underground wiring.
Typical Applications
- Power distribution
- Industrial lighting circuits
- Underground installations
- Fixed wiring in buildings
ALUPY Cables
ALUPY is an aluminum power cable with PE insulation and PE outer sheath. It is used primarily for long-distance power distribution where weight and cost are critical factors.
Typical Applications
- Outdoor power distribution
- Long cable runs
- Underground installations
- Cost-optimized industrial wiring
HOTDRN Cables
HOTDRN is a heat-resistant industrial cable designed for high-temperature environments. It is used in machinery, heating systems and industrial processes where standard PVC cables would degrade.
Typical Applications
- Heating equipment
- Industrial ovens
- High-temperature machinery
- Environments with thermal cycling
Cable Characteristics Overview
| Cable Type | Conductor | Insulation / Sheath | Flexibility | Typical Use |
|---|---|---|---|---|
| CYA | Copper | PVC / — | High | Panels, control wiring |
| CYKY | Copper | PVC / PVC | Low | Power distribution, buildings |
| ALUPY | Aluminum | PE / PE | Medium | Outdoor & underground power |
| HOTDRN | Copper | Heat-resistant insulation | Medium | High-temperature equipment |
Temperature Ratings & Current Capacity
| Cable Type | Temperature Rating | Typical Current Capacity | Voltage Rating |
|---|---|---|---|
| CYA | 70°C (PVC) | 10–200 A | 450/750 V |
| CYKY | 70°C (PVC) | 10–250 A | 0.6/1 kV |
| ALUPY | 70°C (PE) | 5–200 A | 0.6/1 kV |
| HOTDRN | 90–180°C | 10–150 A | 300/500 V or 450/750 V |
Typical Applications
| Cable Type | Common Applications |
|---|---|
| CYA | Panels, switchboards, bonding, control circuits |
| CYKY | Industrial wiring, lighting, power circuits, underground |
| ALUPY | Long-distance power distribution, outdoor feeders |
| HOTDRN | Ovens, heaters, high-temperature machinery |
Summary
CYA is ideal for panel wiring, CYKY for fixed industrial installations, ALUPY for long-distance power distribution, and HOTDRN for high-temperature environments. Understanding conductor material, insulation type, temperature rating and current capacity ensures correct cable selection and safe operation.
