PVC insulated fork terminal high conductivity general purpose durable

In an age where electrical reliability determines operational success, the need for rugged, versatile terminals is growing. From industrial machinery that withstands extreme temperatures to automotive systems that endure constant vibration, components with strong electrical conductivity and insulation are needed. Our PVC insulated fork terminals meet this requirement, combining laboratory-grade electrical performance with real-world durability.

Versatility for a variety of applications

PVC insulated fork terminals can easily adapt to scenarios where conductivity and safety are critical:

Automotive & Marine: Secure battery connections, alternator wiring, and trailer wiring harnesses exposed to engine heat, road salt, and moisture. Fork-shaped design allows for easy removal for maintenance without cutting wires.

Industrial machinery: Wire motor controls, CNC equipment and conveyor systems requiring vibration-resistant connections in dusty or oily environments.

Renewable Energy: Connect solar inverters, wind turbine junction boxes and battery banks using UV-resistant insulation suitable for outdoor exposure.

HOME & DIY PROJECTS: Repair appliances, HVAC systems, or garage tools with color-coded insulation (red, blue, yellow) to instantly identify wire size.

Heavy Duty Switchboards: Terminating thick 250MCM cable in commercial breaker panels or generator installations is supported by the enhanced design of the SV22 model.

The universal fork fits standard 3.0mm-11.0mm studs, and the PVC insulating sleeve prevents accidental shorts in crowded panels. Six sizes accommodate wire gauges from delicate 22 AWG electronics to industrial 250MCM power cord, eliminating the need for multiple terminal types.

Excellent electrical conductivity

Made from 99.9% oxygen-free copper (C11000), the PVC insulated fork terminals have a conductivity of 100% IACS international annealed copper standards to minimize energy loss. The tinned surface resists oxidation, and the contact resistance remains at <2mΩ after more than 1,000 thermal cycles. Unlike aluminum or steel alternatives, the copper core ensures a steady flow of current under heavy loads without overheating. The serrated crimping area firmly bites stranded or solid wire, and the open barrel design allows 360° compression for a gas-tight connection. Laboratory testing confirms a pull-out force of 70N, making it an ideal choice for elevator systems, robots or vibrating diesel generators.

Strong insulation performance

PVC insulated sleeves are more than just a barrier, they’re a multi-layered defense system. Rated to 600V AC/DC and a temperature range of -40°C to 105°C, they withstand arc flash, oil leaks, and abrasion. PVC insulated fork terminals feature a double-wall construction with a flame-retardant PVC outer layer that self-extinguishes in 10 seconds, critical for industrial control panels, and a flexible PVC inner layer that buffers wires from vibration fatigue and prevents cracks in the insulation of hydraulic machinery or off-road vehicles. Color-coded sleeves simplify large-scale installations, and flared insulating rings prevent the sleeve from cracking during the crimping process. Tested to IP54 standards for protection against dust and moisture, they’re ideal for food processing plants, marine battery packs, or outdoor LED arrays.

Conclusion

PVC insulated fork terminals go beyond traditional electrical components, offering a rare triple function of conductivity, adaptability, and armored insulation. Allowing users to replace multiple dedicated terminals with a universal solution can significantly reduce inventory costs and installation errors. Whether it is fixing the battery pack of a hybrid car or a robot arm in a factory, PVC insulated fork terminals ensure that every connection remains efficient, safe, and maintenance-free.
