Cbb80 Lamp Power Factor Plastic Shell Compensation Capacitor Suppliers

CBB80 Plastic-Shell Lamp Compensation Capacitors Built at Our Cixi Plant

CIXI RIYI CAPACITOR FACTORY produces the CBB80 lamp power factor plastic shell compensation capacitor at our plant on the south bank of Hangzhou Bay in Cixi, Zhejiang. The capacitor connects across the lamp supply of high-pressure sodium and other discharge lighting, supplying leading reactive current that offsets the lagging displacement of the magnetic ballast and returns fixture power factor toward unity.

As China Cbb80 Lamp Power Factor Plastic Shell Compensation Capacitor Suppliers, we deliver every plastic-shell model as one complete build: dielectric element, plastic case, VDE lead wire, integral fuse, discharge resistance and screw fixing. Capacitance options of 12 µF, 20 µF and 45 µF at 250 V and 85 °C let one qualified part family compensate several lamp wattages inside the same fixture programme.

Our Plastic-Shell CBB80 Range

Voltage, temperature and the built-in protection set are identical across the group. Capacitance is the selection variable that ties the capacitor to lamp wattage and ballast current.

Selecting Between 12 µF, 20 µF and 45 µF

Higher lamp wattage and higher ballast magnetising current call for a larger capacitance value. The chart shows the three plastic-shell values side by side on the same scale.

Rated capacitance in µF, 250 V, 85 °C. Values are matched to the lamp and ballast combination rather than to fixture size.

Dielectric, Case and Internal Build

The element is a high-temperature-resistant polypropylene film wound as a non-inductive section, then housed in a plastic shell. Each finished part carries the same protective set, which is what allows the AC Cbb80 plastic shell compensation capacitor to sit inside a sealed luminaire for years of continuous energisation.

• Polypropylene film winding — non-inductive construction with a high-temperature film grade suited to sustained lighting duty.
• Plastic shell — a compact insulating case that keeps the winding mechanically supported and electrically isolated from the fixture body.
• Integral fuse — an internal protective element that clears the circuit if the winding fails, limiting stress on the ballast and wiring.
• Discharge resistance — bleeds stored charge after the supply is removed so the terminal pair does not hold a hazardous voltage during service.
• VDE lead wire and screw fixing — insulation rated for mains lighting circuits, with a screw provision that anchors the capacitor to the fixture plate.

Where the Plastic-Shell CBB80 Fits

CBB80 is a lamp-side compensation capacitor. It is specified where a discharge lamp with magnetic ballast runs on a supply with a power factor requirement.

• High-pressure sodium street, roadway and car park lighting.
• Industrial high-bay and low-bay discharge fixtures.
• Floodlighting and area lighting built around magnetic ballasts.
• Retrofit compensation added to existing discharge fixtures during relamping programmes.
• OEM luminaire assembly where the capacitor is fitted on the production line.

Motor-run and motor-start duty is served by a different dielectric group rather than by CBB80. Our AC Cbb60, Cbb61, Cbb65, Cbb80 capacitor range covers pump, compressor, fan, washing machine and air-conditioning motors with the appropriate case style and termination.

Shell Options and Temperature Class

The plastic shell covers demanding but not extreme ambient conditions. Where a fixture runs hotter or the mechanical envelope calls for a metal can, the same electrical duty is met by CBB80 aluminum housing compensation capacitors, which are available in 105 °C versions.

Plastic shell — 250 V, 85 °C

Aluminum housing — up to 105 °C

Mounting and Wiring Points We Confirm With Fixture Builders

• Capacitor position relative to the ballast, so ambient rise at the case is understood before the 85 °C rating is applied.
• Lead routing and lead length available on the VDE line for the fixture wiring layout.
• Screw fixing position and plate thickness on the mounting bracket.
• Terminal accessibility for production testing and for later field service.

Manufacture, Testing and Certification

Winding and slitting are carried out on our own equipment inside a 25,000 m² plant, with 11 automatic slitting machines and 15 automatic imported winding machines supporting a daily output of 60,000 pieces. Film, case, lead wire and protective elements are assembled as a single controlled build, not sourced as a finished trade part.

Information We Use to Configure Your Solution

Send these details with your enquiry and we can pin the model, the termination and the packing before quoting. Where a fixture needs a value outside 12 µF, 20 µF and 45 µF, we develop a custom part from your drawing or sample.

1. Lamp type and wattage, and the ballast or control gear used.
2. Required capacitance value and target power factor at the fixture.
3. Supply voltage and frequency at the installation.
4. Ambient temperature at the capacitor position inside the luminaire.
5. Preferred shell option — plastic or aluminum housing — and the mounting space available.
6. Termination and lead length required for the wiring layout.
7. Approval requirement for the destination market.
8. Order quantity, packing preference and labelling.
9. Drawing or physical sample for non-standard values.

Frequently Asked Questions

Which capacitance do I need for my lamp?

The value follows the lamp and ballast combination rather than the physical size of the fixture. Give us the lamp type, wattage and ballast details and we will confirm whether the 12 µF, 20 µF or 45 µF plastic-shell model suits your working point.

Can the CBB80 plastic-shell capacitor run a motor?

No. This group is built for lamp-side power factor compensation on discharge lighting. Motor-run and motor-start duty is covered by our CBB60, CBB61 and CBB65 capacitor types, and we will point you to the right family for the motor application.

What do the fuse and resistance inside the capacitor do?

The fuse is an internal protective element that clears the circuit on winding failure, protecting the ballast and luminaire wiring. The resistance discharges the winding after the supply is switched off, so the capacitor does not hold a stored charge on the terminals during service work.

Do you build non-standard capacitance values?

Yes. Where a fixture needs a value outside our listed models, we develop and produce the capacitor from your drawing or sample, keeping the same case, protective set and termination approach as the standard plastic-shell build.

How are the capacitors packed and shipped?

Parts are packed to the agreed quantity and labelling and dispatched from Cixi, close to Ningbo for sea freight, with air freight available when a project schedule demands it.

Is the CBB80 plastic shell available alongside other CBB80 formats?

Yes. The plastic shell is one branch of our CBB80 Lamp Power Factor Compensation Capacitor Manufacturers range, which also includes the aluminum housing branch for higher ambient temperatures and metal-can builds.
