Pre-insulated cold-pressed terminals: Build a safe, reliable, and durable connection point for your electrical circuits



Pre-insulated cold-pressed terminals are essential accessory products designed for creating secure and efficient electrical connections. Often referred to as OT terminals or preinsulated terminals, these components are primarily constructed from brass and insulated with durable polyvinyl chloride (PVC). Supporting a maximum voltage of 300V and temperatures up to 75°C, they provide a reliable cold pressed connection that is both safe and long-lasting. With their rational design and straightforward installation, this practical terminal block set ensures an excellent user experience across various applications.
Product Features
Integrated Insulation Protection: Made from flame-retardant polyvinyl chloride (PVC), the fully enclosed insulation design resists heat and fundamentally prevents electric shock and short-circuit risks.
Reliable Permanent Connection: These cold-pressed terminals form a sturdy, durable connection that resists pulling, vibration, and loosening while maintaining stable conductivity.
Color-Coded Standardization: Wire cross-sections are easily distinguished by color, allowing for quick identification and selection of the correct terminal blocks and specifications.
Efficient Installation: Simple operation enables a secure cold pressed connection in one step, delivering consistent quality and reducing reliance on operator skill.
Available Models:
Applications:
Industrial Automation & Control Systems: Ideal for distribution panels, motor wiring, sensors, actuators, and internal equipment wiring where reliable terminal blocks are critical.
Transportation: Preinsulated terminals in this field demand high vibration resistance, temperature tolerance, and overall connection reliability.
Home Appliances: Perfect for repairing and extending household circuits using pre-insulated terminals for safe and durable connections.
DIY Projects: Excellent for establishing reliable cold-pressed connections between development boards and sensors or actuators.
Pre-insulated cold-pressed terminals are ubiquitous—from high-precision industrial equipment to everyday household applications. With integrated insulation protection, permanent vibration-resistant and anti-loosening performance, and convenient installation, they create safe, reliable, and durable connection points for diverse electrical systems. These preinsulated terminals serve as trusted electrical components for modern electricians, engineers, and DIY enthusiasts.
