Product Description

Pre-insulated ring terminals (RV series) are widely used in power distribution sectors - including distribution cabinets, power supply equipment, transformers, industrial and construction machinery, and automation systems - making them an ideal choice for control cabinet assembly and electrical installation projects.

The wire connection section is made of specially coated copper to enhance resistance to oxidation, acids, alkalis, and corrosion, ensuring connection stability and durability over a long service life. Precision-engineered mounting holes ensure a perfect fit, uniform load distribution, vibration resistance, and a secure connection.

These terminals feature heat-resistant PVC insulation sleeves that tightly encase the connection point, preventing accidental contact with live parts, short circuits, or liquid ingress, thereby enhancing overall system safety.

Utilizing cold-press connection technology eliminates the need for soldering or high-temperature processing, which accelerates installation, simplifies on-site operations, and improves workflow efficiency.

The products are color-coded (red, yellow, blue, black) to correspond with different wire cross-sections, facilitating easy identification and helping to prevent wiring errors. They comply with IEC standards for low-voltage electrical connections and are highly suitable for power supply and control signal transmission systems.

FAQ

Q1: What are RV series pre-insulated ring terminals, and where are they primarily used?

A: RV series pre-insulated ring terminals are solderless (crimp-style) connectors used to establish electrical connections between wires and screw-type terminals. They are widely used in low-voltage power distribution equipment-such as distribution boxes, control panels, motors, automation equipment, construction machinery, and grounding circuits-to ensure secure and consistently reliable connections.

Q2: What materials are used in the product? Is the insulation sleeve flame-retardant?

A: The terminal body is made of high-purity copper with a tin-plated finish to prevent oxidation and corrosion. The insulation sleeve is made of flame-retardant PVC material, providing insulation protection for the wire and preventing short circuits or electrical leakage.

Q3: What are the rated voltage and operating conditions?

A: Maximum voltage: 600V; operating temperature: -40°C to +105°C. Storage temperature range: -45°C to +125°C; altitude: ≤2000 meters; humidity: ≤95% (non-condensing). The product is suitable for indoor and outdoor use in general environments; however, prolonged exposure to ultraviolet (UV) radiation or flammable gas environments should be avoided.

Q4: Is soldering required during installation? Can they be reused?

A: This product is a crimp-style (solderless) connector; no soldering is required. A secure crimp can be achieved simply by using the appropriate tool. Once crimped, only the metal part remains visible; reuse after disassembly is not recommended, as it may compromise connection performance and increase contact resistance.
