Product FAQs
Q1: Why do New Energy Vehicles (EVs) require shielded (EMC) cable glands?
A: Electric vehicles utilize high-power electric motors and high-voltage battery systems that generate significant electromagnetic interference (EMI) or magnetic waves. To ensure sensitive low-voltage sensors, electronic control units (ECUs), and communication lines operate smoothly without interference, the cables must be shielded. A shielded cable gland seamlessly connects the cable’s braid/shielding layer to the grounded metal enclosure, establishing a continuous 360-degree grounding path to suppress EMI.
Q2: How effective is your anti-loosening design in high-vibration environments?
A: Highly effective. Unlike standard cable glands that rely solely on thread tension, our shielded cable glands feature an optimized clamping claw mechanism. Once tightened, the internal claws grip a large surface area of the cable sheath with mechanical locking force. This robust construction prevents cable movement or connection loosening, even under the continuous vibration typical of EVs and heavy industrial machinery.
Q3: Which material option is best for long service life and optimal protection?
A: For highly corrosive or extreme environments (such as offshore marine or aggressive chemical facilities), we recommend 316L stainless steel (SS316L). However, for standard industrial applications, automotive infrastructure, and automation projects, our standard nickel-plated brass offers an outstanding balance of durability, corrosion resistance, and cost-effectiveness.
Q4: Can we customize the cable clamping range or specific thread lengths?
A: Yes. As a direct manufacturer, we support extensive technical OEM/ODM customization. We can supply dedicated internal seals to fit non-standard cable outer diameters or precision-machine extended threads to meet specific enclosure mounting requirements.
