Rapid Connection & Flexible Adaptation – Copper Open Terminal

1.Introduction to OT Copper Open Terminal

The OT copper open terminal (Open Type Copper Terminal) is a copper electrical connection terminal designed for quick and flexible wire connections. Its “open” design allows wires to be inserted or removed without complete crimping, making it ideal for scenarios requiring frequent maintenance or temporary connections.

2.Main Application Fields

1. Industrial Power Distribution Systems

• Wire connections in distribution cabinets and control panels for easy maintenance and circuit adjustments.

1. Building Electrical Engineering

• Temporary power connections, such as for construction lighting, improving installation efficiency.

1. Power Equipment Manufacturing

• Used in factory testing and wiring of motors, transformers, and other equipment.

1. New Energy Sector

• Rapid wiring needs for solar power stations, charging stations, and other renewable energy equipment.

1. Rail Transit and Marine Applications

• Vibration-prone environments where frequent disconnections are required.

3.Core Advantages

1. Quick Installation & Disassembly

• Operated manually or with simple tools via the open design, eliminating the need for specialized crimping equipment.

1. High Conductivity & Safety

• Pure copper material (99.9% conductivity) reduces resistance and heat risks.

1. Strong Compatibility

• Supports multi-strand flexible wires, solid wires, and various conductor cross-sections.

1. Reliable Protection

• Enclosures prevent exposed wires, avoiding short circuits or electric shocks.

4.Structure & Types

1. Materials & Process

• Main Material: T2 phosphorus copper (high conductivity), surface plated with tin/nickel
• Fastening Method: Spring clamps, screws, or plug-and-pull interfaces.

1. Common Models

• Single-Hole Type: For single-wire connections.
• Multi-Hole Types: For parallel or branching circuits.
• Waterproof Type: Featuring sealing gaskets for wet environments (e.g., basements, outdoors).

5.Technical Specifications

6.Installation Steps

1. Wire Stripping: Remove insulation to expose clean conductors.
2. Insertion: Insert the wire into the open end and adjust depth.
3. Fixation: Tighten using screws or clamps to ensure secure contact.
4. Insulation Protection: Apply heat shrink tubing or tape to exposed parts if necessary.

7.Notes

1.  Choose the correct model based on conductor cross-section to avoid overloading.
2. Inspect for loose clamps or oxidation after prolonged use.
3. Use waterproof types in humid environments; reinforce installations in high-vibration areas.

The OT copper open terminal delivers rapid installation, high conductivity, and flexible adaptability, making it ideal for industrial, new energy, and construction applications requiring frequent maintenance or dynamic connections.
