TECHNICAL Specification
Partex cable lugs, specifically the PXL series for copper tube terminals, are designed for high-conductivity copper cable terminations, often used with copper tube terminals and compression connectors. They are generally manufactured from high-grade copper (often BS EN 1976) and annealed to ensure high conductivity and flexibility for crimping.
- Material: High conductivity copper (C11000/BS EN 1976).
- Coating: Electrolytically tin-coated to increase corrosion resistance.
- Design: Bell-shaped cable entry for easy insertion and a pre-crimping inspection window to verify proper conductor positioning.
- Application: Suitable for copper compression lugs (PXL series) ranging from 1.5mm² to 630mm².
- Compliance: PXL lugs generally comply with BS6360 (standard electrical cables) and PXP pin-type lugs meet BS EN 61238.1:2003 for compression joints.
Partex PXL lugs are sized based on metric wire sizes (
) and stud sizes.
- Size Range: 1.5mm² to 630mm².
- Stud Hole Sizes: Available for M5 to M20 screws.
- Examples:
- PXL10-10: 10mm² cable, 3/8″ (10mm) stud.
- PXL35-10: 35mm² cable, 3/8″ (10mm) stud.
- PXL120-12: 120mm² cable, 1/2″ (12mm) stud.
- PXL150-14: 150mm² cable, 9/16″ (14mm) stud.
- PXL185-12: 185mm² cable, 1/2″ (12mm) stud.
- PXL630-X: Sizes up to 630mm².
Partex also offers pre-insulated terminals for various conductor sizes, often identified by color code:
- Material: C1100 Copper with PVC insulation.
- Temperature Rating: -20°C to +75°C.
- Max Voltage: 600 Volt.
- Color Codes:
- Red: 0.5–1.5mm² (22-16 AWG).
- Blue: 1.5–2.5mm² (16-14 AWG).
- Yellow: 4.0–6.0mm² (12-10 AWG).
- Material: Tin-coated high conductivity copper (Purity >99.9%).
- Insulation: Polyamide 66.
- Temperature Range: -40°C to +105°C.
- Standards: DIN 46228-4.
- Voltage: Suitable for circuits not exceeding 1000V (depending on the type).
- Compression: Designed to provide a reliable, low-temperature connection when used with recommended crimping tools.
- Vibration Resistance (VR): Specific to extra-copper ring terminals, providing extra support against vibration.
Overview & Usage
Partex cable lugs are high-quality, typically tin-plated copper terminals designed for secure and reliable termination of copper cables in electrical systems. They are widely used in industrial, commercial, and residential applications for power distribution, electrical panels, and switchboards.
- Material: Made of high-conductivity annealed copper (to BS EN 1976), with electroplated tin coating to enhance conductivity and improve corrosion resistance.
- Design: Feature a bell-shaped entry for easy cable insertion and a small inspection hole to ensure the conductor is fully inserted before crimping.
- Type: Primarily compression-type (crimp) lugs for creating a strong, almost homogeneous electrical joint.
- Size Range: Comprehensive range available to fit conductors from 1.5mm² up to 630mm².
- Temperature Rating: Designed to withstand high temperatures, with some models rated up to 180°C.
- Compliance: Meets BS6360 standards for cable fit and BS EN 61238-1:2003 for compression joints.
- Termination: Used to safely terminate copper conductors at switchgear, transformers, and busbars.
- Panel Building: Frequently used by panel builders for secure and durable connection in electrical control panels.
- Cable Types: Designed for standard electrical cables, including BS6360 and TRI-RATED (BS6231).
- Installation: Installed using specialized crimping tools.
- Specialized Lugs: Includes “Pin Type” uninsulated lugs (e.g., PXP10) for specific terminal constraints.
- PXL Lugs: Standard metric tin-coated copper compression lugs.
- COL Terminals: Copper tube crimp terminals.
- PXP Terminals: Pin-type uninsulated lugs.
- Pre-insulated Terminals: Included in the broader Partex terminal range for various cable sizes.
