Jinhua Dika Electrical Equipment Co., Ltd. presents the DT-50 Cable Lug, a premium termination solution designed specifically for 50mm² national standard wire. Manufactured in our ISO9001-certified facility in Jinhua, Zhejiang, China, this cable lug combines high-purity copper with precision engineering to ensure reliable electrical connections in power distribution, industrial control, and renewable energy systems. With over a decade of export experience and annual export value exceeding US$1 million, we deliver products that meet rigorous quality standards while offering competitive pricing. Each DT-50 lug comes with a 1-year warranty, reflecting our commitment to customer satisfaction.
Our cable lugs are produced using oxygen-free copper (copper content ≥99.9%) and undergo strict quality checks including tensile strength tests, conductivity measurements, and salt spray corrosion resistance tests. The DT-50 model is specifically engineered to accept 50mm² stranded wire while providing a secure mechanical grip and maximum electrical conductivity. Whether used in switchboards, motor connections, or junction boxes, this lug ensures low contact resistance and long service life even under high current loads.
Key Features & Technical Specifications
- Material: High-purity T2 copper (≥99.9%) – ensures excellent conductivity and ductility.
- Surface Finish: Available in bare copper or tin-plated finish. Tin plating provides superior corrosion resistance and solderability.
- Wire Size: Designed for 50mm² (≈1/0 AWG) stranded copper wire, following national standard dimensions.
- Barrel Design: Precision-machined barrel with chamfered edges for easy wire insertion; internal groove prevents wire pull-out.
- Pal Nut: Smooth, burr-free pal nut ensures safe crimping and eliminates sharp edges that could damage insulation.
- Voltage Rating: Suitable for up to 1kV installations (as per typical application).
- Temperature Range: -40°C to +105°C (depending on cable insulation).
- Standards Compliance: Manufactured in accordance with GB/T 14315-2008 national standard for cable lugs, compatible with international standards like IEC 61238-1.

Q: What crimping tool should I use?
A: We recommend a hexagonal or indent-style crimping tool with a die size corresponding to 50mm² (e.g., die mark 50). The lug accommodates standard crimping profiles. -
Q: Does the lug come with a plastic insulation sleeve?
A: The standard DT-50 is bare (no insulation). Insulated versions (with PVC sleeve) are available upon request under model DT-50I. -
Q: What is the maximum current rating for this lug?
A: Based on 50mm² copper wire at 70°C ambient, the typical current rating is 150–180A in air. Final rating depends on installation conditions. -
Q: Do you provide samples before bulk order?
A: Yes, we offer free samples (customer pays shipping) for evaluation. Lead time is 3–5 days. -
Q: Can I get the lug with a different hole diameter?
