The DTL-1 Copper-Aluminum Terminal provides cost-effective bimetal connectivity for standard electrical installations, utilizing friction-welded T2 copper and L3 aluminum to minimize electrochemical corrosion risks while maintaining reliable conductivity in dry or controlled environments. Designed for copper-to-aluminum transitions in low voltage systems (10kV), this GB/T-compliant terminal features a semi-circular crown design and dual-hole variants for flexible cable termination in distribution cabinets, residential switchgear, and light industrial machinery. Its simplified structure omits conductive gel chambers and dust-proof seals, prioritizing affordability for applications like indoor transformer connections and small-scale power distribution retrofits. While not recommended for high-vibration environments or aluminum alloy cables due to reduced wall thickness compared to European-standard models, it remains a practical solution for maintenance-monitored systems requiring IEC 61238-1-certified performance at 25% lower lifecycle costs than premium alternatives. Ideal for urban grid upgrades and commercial facility expansions where humidity and temperature fluctuations remain moderate.
