High Voltage Terminals are critical components in electrical systems where high voltage stability, insulation performance, and operational safety are non-negotiable. At Précision Qianwei, we design and manufacture high-performance high voltage terminals engineered to meet the demanding requirements of electric vehicles, energy storage systems, industrial power equipment, and renewable energy applications.
With precision manufacturing, strict quality control, and OEM-level customization capabilities, our high voltage terminals ensure secure electrical connections, minimized power loss, and long-term reliability in high-stress environments.
Engineered for High Voltage Performance & Safety
Our high voltage terminals are developed to withstand extreme electrical loads while maintaining excellent insulation and mechanical strength. Each design is optimized to control creepage distance, dielectric strength, and contact stability, reducing the risks of arcing, overheating, and electrical failure.
Key performance benefits include:
-
High voltage withstand capability for demanding power systems
-
Excellent insulation resistance and dielectric strength
-
Low contact resistance for stable and efficient power transmission
-
Arc suppression and anti-corona structural design
-
Long service life under vibration, heat, and harsh environments
Advanced Materials & Structural Design
Material selection and structural integrity are critical in high voltage environments. Qianwei high voltage terminals are manufactured using high-conductivity copper or copper alloy contacts combined with high-grade insulation materials such as PA, PBT, PPS, or silicone-based compounds.
Design features include:
-
Reinforced insulation walls to increase creepage and clearance distances
-
Anti-tracking and flame-retardant insulation materials
-
Secure terminal retention and locking structures
-
Optimized contact geometry for stable current flow
These features ensure consistent performance even in compact, high-density power systems.
