Name: China DTL‑C Bimetal Connectors Manufacturers Suppliers Factory - Customized Service - Jasco Electric
Brand: Jasco
SKU: 319632294

Product Description

The DTL-C-630 series, manufactured by Jasco, consists of bimetallic (copper-aluminum) cable lugs and connectors widely used in renewable energy, industrial power distribution, power generation, and other technical sectors.

The aluminum section of the product is specifically designed for connecting aluminum conductors, while the copper palm is intended for connection to copper busbars, circuit breakers, and other copper components.

This design effectively prevents electrochemical corrosion caused by direct contact between copper and aluminum, thereby reducing corrosion risks and avoiding operational failures.

The series operates within a temperature range of -40°C to +125°C and is suitable for voltage systems ranging from 0.6kV to 1kV.

A variety of conductor cross-sections (35mm² to 400mm²) are available to meet specific application requirements. The products are manufactured in strict accordance with the GB/T 14315-2010 standard. Additionally, the series supports laser marking and can be produced according to OEM specifications or packaged to meet customer requirements.

FAQ

Question 1: Which company manufactures the DTL-C-630 bimetallic (copper-aluminum) cable lug?

Answer 1: This product is manufactured by Yueqing JASCO Electric Co., Ltd., located in Yueqing City, Zhejiang Province, China.

Question 2: What is the function of the DTL-C-630 model?

Answer 2: The DTL-C-630 is a copper-aluminum connector (bimetallic transition lug). Its aluminum section is designed for connecting aluminum power cables, while the copper section (flat contact pad) is used for connections to circuit breakers, transformers, and copper conductors. This product effectively minimizes electrochemical corrosion caused by direct contact between copper and aluminum.

Question 3: What manufacturing process is used?

Answer 3: We employ friction welding and composite casting technologies. These processes create a strong metallic (metallurgical) bond between the copper and aluminum, ensuring the connection does not detach, separate, or break.

Question 4: What raw materials are used for the DTL-C-630?

Answer 4: Copper section (terminal pad): High-purity T2 copper; Aluminum section (crimping barrel): High-purity 1060 aluminum. The product offers high electrical conductivity and excellent mechanical strength.

Question 5: What are the specifications for the DTL-C-630?

Answer 5: This model covers a range of specifications suitable for cross-sectional areas from 35 mm² to 400 mm² (e.g., DTL-C-630-35, 50, 70, 95, 120, 150, 185, 240, 300, and 400).
