Common Questions About Cable Accessories
Q1: Do you offer both Cold Shrink and Heat Shrink accessories?
A: Yes, 4E manufactures both types to suit different installation environments. Our Cold Shrink accessories are ideal for limited-space areas and require no special tools, while our Heat Shrink kits offer exceptional mechanical protection and weather resistance. We can recommend the best solution based on your voltage level and project conditions.
Q2: Are your Cable Lugs and Ferrules compatible with aluminum cables?
A: Absolutely. We provide a full range of connectors, including Copper (Cu), Aluminum (Al), and Bimetallic (Cu-Al) lugs. Our bimetallic lugs are specifically engineered to connect aluminum cables to copper busbars, preventing galvanic corrosion and ensuring a stable electrical connection.
Q3: Can 4E cable accessories be used with other brands of cables?
A: Yes. Our accessories are designed in strict accordance with international standards (such as IEC and DIN), making them compatible with most global cable brands. However, for the highest level of system integrity and safety, we recommend pairing them with 4E’s own Power Cables.
Q4: Do you provide installation instructions for High Voltage joints?
A: Safety is our priority. All 4E High and Medium Voltage accessory kits come with detailed installation manuals. Additionally, our technical team is available to provide remote guidance or on-site support for complex grid projects.
Q5: Can I customize the Grounding Box or accessory kits?
A: As a manufacturer with integrated R&D capabilities, 4E supports OEM and ODM services. We can customize Grounding Boxes (link boxes) and accessory kit components to meet specific utility requirements or environmental standards.
