AC Cbb65 Wire Lead Explosionproof Capacitor Suppliers

Wire-Lead CBB65 Explosion-Proof Capacitors from Our Own Plant

Cixi Riyi Capacitor Factory produces the AC Cbb65 Wire Lead Explosionproof Capacitor Suppliers group in Cixi, Zhejiang, China: metallized polypropylene film capacitors that hold a stable phase shift between the main and auxiliary currents of a single-phase motor. Wire leads replace terminals, so the part is wired directly into washing machines, dryers, air conditioners, range hoods, water pumps, circulation fans and compressor motors.

We are a China-based capacitor manufacturer running 25,000 m² of plant with 11 automatic slitting machines and 15 imported winding machines, at a daily output of 60,000 pieces. Standard values come from tooling we already hold; capacitance, lead length, inductance and fixing geometry are built from your drawing or sample.

Three Build Directions Inside the Lead Group

Lead Models We Build

S2 construction is used on most lead models and S3 on selected ones; S3 parts in this group are supplied with an explosion-proof plastic shell and a sheath line. Terminal-type versions are covered by our AC Cbb65 Insert Type Explosionproof Capacitor Suppliers group.

Single Values at 450V

Column height shows relative capacitance value across the 450V lead models.

Dual-Run Sections We Hold

Bar length tracks the main section value; colour-marked leads identify each section on dual parts.

Where the Lead Type Concentrates

The lead family carries its weight in direct wire connection and mounting flexibility rather than in a single narrow value band. Capacitance spread, inductance variants and mounting hardware are the three dimensions we extend most often during development.

Application Fit and Operating Boundaries

Lead models are specified for continuous AC operation of single-phase motors. The capacitance creates the phase shift for starting and running torque; the film system gives low loss, high insulation resistance and self-healing behaviour across the CBB65 range. Ambient temperature, duty cycle and lead routing determine whether a standard 85 °C model is used or whether a sheath-line S3 part with an explosion-proof plastic shell suits the enclosure better.

• Washing machines, dryers, air conditioners and range hoods with a wired capacitor pocket
• Water pumps, compressors and blowers where a terminal block is not present — our AC Cbb60 Water Pump Water Pump Motor Capacitor Manufacturers series covers the axial plastic-case route
• Fans and ventilation motors from 2µF up to 5µF at 450V, and 35µF at 300V for heavier loads
• Dual-value circuits where one capacitor runs the compressor section and the second runs the fan section

Quality Control and Acceptance

We agree the acceptance plan with you before production: capacitance and tolerance, voltage rating, capacitance class, insulation resistance, lead length and gauge, inductance value where fitted, case marking and packing. Slitting, winding and assembly stages are monitored in-house, and finished parts are held to the agreed inspection items for the shipment. Model, capacitance, voltage, class and lead configuration are printed on the case so a replacement matches the original position without guesswork.

Information We Use to Configure Your Solution

A drawing or a sample of the part being replaced is the fastest route for us to confirm dimensions, lead orientation and class. Send those details with the motor rating and we return a configured offer with the drawing, packing data and shipment terms agreed.

Installation, Maintenance and Spares

Mount the capacitor where its rating faces the correct motor winding, keep the lead strain free and respect the creepage distance to metal parts of the chassis. Discharge the part before any service work, and renew a capacitor when capacitance falls outside tolerance or the case shows deformation.

We keep the model designation stable on the case so spare lists stay valid across batches, and we document capacitance, voltage, class and lead configuration for your bill of materials. Technical personnel and engineers at the plant support routing questions, replacement matching and custom development on drawings or samples.

Frequently Asked Questions

1. What distinguishes the lead type from other CBB65 capacitors?

Lead models terminate in flexible wire instead of a terminal block, which suits appliances that connect the capacitor directly into a wiring harness. They keep the same explosion-proof case design and film system as the rest of the AC CBB65 Explosion-Proof Capacitor Manufacturers range, including the insert and terminal versions.

2. Which values can be ordered with wire leads?

Single values run from 2µF to 40µF across 250V, 300V, 450V and 500V, with 6µF, 8µF, 10µF, 12µF and 20µF at 450V held as standard. Dual sections include 13+5µF and 14.5+4.5µF at 500V, 15+10µF, 15+5µF, 16+9µF at 450V, 18+7µF at 500V and 66/24µF at 300V.

3. What do S2 and S3 mean on these models?

S2 and S3 are the explosion-proof construction classes we build inside the CBB65 lead range. Most lead models are S2, while selected parts are S3 and use an explosion-proof plastic shell with a sheath line. The class that suits your assembly is confirmed at configuration, together with case size and fixing method.

4. Can capacitance, lead length or fixing be customised?

Yes. We develop from your drawing or sample, covering capacitance value, tolerance, lead length and gauge, inductance, sheath line, screw, mounting plate, mounting ferrule, middle installation slot and contact piece, plus case marking.

5. Which applications use the dual-value lead capacitors?

Dual-value parts serve circuits with two windings in one housing, such as air-conditioning units running a compressor section and a fan section from the same capacitor. Colour-coded leads identify each section so the wiring position is unambiguous during assembly or replacement.

6. How are the capacitors packed and shipped?

Parts are packed to the agreed carton and pallet format for the quantity ordered. Shipment is normally by sea from Ningbo, with air freight available when timing is tight, and payment terms such as T/T or L/C are settled when the offer is confirmed.
