Name: China DTL‑2F Bimetal Lugs Manufacturers, Suppliers and Factory - Customized Service - Jasco Electric
Brand: Jasco
SKU: 319632246

Product Description

DTL2 series terminal lugs are widely used in power optimization, industrial power distribution, and power supply system infrastructure.

To prevent electrochemical corrosion caused by direct contact between copper and aluminum, the product features a composite structure combining an aluminum body with a copper barrel: the aluminum section connects to aluminum cables, while the copper section connects to busbars, transformers, and switchgear. This design prevents overheating during long-term operation and reduces the risk of corrosion.

The materials used in DTL2 terminals offer excellent flame retardancy and tensile strength, as well as superior oxidation and corrosion resistance. With a wide operating temperature range (-40°C to +125°C), these terminals are suitable for high-voltage (0.6/1 kV) indoor and outdoor power distribution systems.

DTL2 terminal specifications range from 10 mm² to 300 mm², complying with the GB/T 14315-2010 standard; customization services are also available to meet specific customer requirements.
