### Specifications

The set includes **220 pieces**, covering various SC-type ring copper terminals (such as SC 6-6, 6-8, 10-6, 10-8, 16-6, 16-8, etc.) and red/black dual-color heat shrink tubing (with different lengths and diameters for compatibility). All components are organized in a transparent sorting box with clearly marked model sections for easy access.

### Materials

- Ring terminals: **High-purity copper** with superior conductivity, oxidation resistance, and corrosion resistance, ensuring stable, low-resistance current transmission.

- Heat shrink tubing: **Insulating heat-resistant material** withstanding temperatures up to 125°C. Shrinks to tightly seal wire connections, providing multi-layered protection against insulation failure, moisture ingress, and abrasion.

### Functionality

- **Stable Electrical Connection**: Copper terminals form secure crimped connections with wires, eliminating loose joints or oxidation-induced contact failure to guarantee stable power supply.

- **Enhanced Insulation Protection**: Heated heat shrink tubing creates a sealed wrap around wiring points, effectively preventing short circuits and leakage for improved electrical safety.

- **Multi-Gauge Compatibility**: A wide range of terminal models accommodates wires of various gauges, including 4AWG, 6AWG, and 8AWG, meeting diverse wiring needs from residential to industrial applications.

### Usage Instructions

1. **Select Compatible Products**: Choose the appropriate copper terminal and heat-shrink tubing based on the wire gauge and terminal specifications.

2. **Crimp the Terminal**: Strip wire insulation, insert copper core into terminal tube, and crimp securely using a crimping tool;

3. **Heat Shrink Protection**:

Slide heat shrink tubing over the crimped joint, then evenly heat with a heat gun or lighter to shrink it tightly around the connection;

4. **Installation and Fixing**:

Connect the crimped wire to equipment terminals and tighten screws to complete installation.

### Applications

- Industrial settings: Distribution box wiring, mechanical equipment electrical systems, marine circuit maintenance;

- Transportation settings: Automotive circuit repair/modification, motorcycle electrical component wiring;

- Residential settings: Internal wiring for home appliances (refrigerators, washing machines, etc.), DIY electronic device assembly, temporary outdoor circuit connections.

### Features

- **One-Stop Solution for Multiple Specifications**: 220-piece set covers 8+ SC terminal models, accommodating various wire gauges to meet all wiring needs;

- **Reliable Copper Conductivity**: High-purity copper terminals offer low resistance and rapid heat dissipation, minimizing overheating during prolonged use to ensure stable operation of high-power equipment;

- **Dual Protection with Heat Shrink Tubing**: Included heat shrink tubing provides insulation, moisture resistance, and abrasion protection. When heated, it forms a sealed protective layer, significantly extending connection lifespan;

- **Organized Storage for Easy Management**: Transparent, categorized storage boxes keep terminals and heat shrink tubing neatly separated. Models are clearly visible, simplifying tool organization, portability, and inventory management.
