Product Description

The BV series insulated butt connectors feature a compact, streamlined design that facilitates rapid installation (including side-by-side mounting).

Internally, they consist of a precision-machined and polished copper tube lined with a vibration-dampening rubber layer, enhancing resistance to rust and corrosion while ensuring reliability in harsh environments.

The connector body is encased in a durable PVC sleeve designed for heat-shrink applications; upon heat shrinking, the sleeve provides immediate protection for the connection point and effectively mitigates risks such as overheating and short circuits. Requiring no soldering and supporting screw-based fixation, these connectors are ideal for rapid on-site wiring tasks.

To facilitate quick cable identification and management, the sleeves are color-coded (red, yellow, and blue correspond to specific wire gauges). Specifications cover cross-sectional areas ranging from 0.5 mm² to 25 mm² (compliant with AWG standards) and support currents of up to 115 amperes.

These connectors are suitable for connecting shielded cables in both indoor and outdoor settings, comply with International Electrotechnical Commission (IEC) standards for low-voltage wiring, and are widely used in high-power electrical equipment applications.

FAQ

Question 1: What are BV series pre-insulated connectors used for?

Answer: BV series pre-insulated connectors are cold-crimp wire connectors designed to join two single-phase conductors and ensure a reliable connection. They are suitable for small-scale power distribution and wiring tasks, such as applications in distribution boxes, junction boxes, machinery, building facilities, automation systems, and grounding circuits.

Question 2: What materials are used? Will the insulation housing crack?

Answer: The internal contact is made of pure copper with a durable surface finish, offering excellent oxidation and corrosion resistance. The outer layer is made of heat-resistant PVC, which protects the conductor and prevents short circuits and arcing.

Question 3: What do the different colors signify?

Answer: Colors are used to distinguish wire gauges: Red (0.5–1.5 mm²), Blue (1.5–2.5 mm²), Black (2.5–4 mm²), and Yellow (4–25 mm²). This coding system facilitates easy identification and helps reduce the risk of cable damage.

Question 4: Is soldering required for installation? Can they be reused after removal?

Answer: No soldering is required; please use the appropriate tool to secure the connection. Since the metal components deform during use, reusing the connector after removal is **not recommended**. Reuse may compromise tensile strength; using a new connector is the best choice.

Question 5: Do you offer custom designs or create drawings for customers?

Answer: We provide OEM manufacturing services, including custom solutions and customer logo printing. Minimum costs and any additional charges depend on specific requirements.

Question 6: Do you provide samples? What is the lead time?

Answer: Samples are free, but shipping costs are borne by the buyer. The order processing time is 7 to 15 working days; for many products, the specific delivery date will be determined based on the actual production schedule.
