CBB80 Lamp Power Factor Compensation Capacitor Manufacturers

CBB80 Lamp Power Factor Compensation Capacitor, Built Around Lamp Circuits

Cixi Riyi Capacitor Factory manufactures the CBB80 Lamp Power Factor Compensation Capacitor for luminaires that run on magnetic ballasts: high-intensity discharge lamps, high-pressure sodium and metal halide fixtures, and the industrial lighting assemblies built around them. The capacitor supplies the reactive current the ballast draws, lifting the power factor at the fixture and reducing the current carried by the supply cable.

Every model uses a polypropylene film winding in a compact housing, supplied with a screw fixing, an internal electric fuse and a discharge resistance. Choose an aluminum housing where the luminaire runs hot or the capacitor sits inside a closed gear compartment, or a plastic shell model for open trays and standard 250 V fixtures.

Two Housing Groups Across Our CBB80 Range

As CBB80 Lamp Power Factor Compensation Capacitor Manufacturers, we build both housing groups on one electrical platform and separate them by housing material, temperature class and termination.

Where the Compensation Capacitor Sits in the Lamp Circuit

1. The magnetic ballast draws a lagging current from the mains through the luminaire.
2. The CBB80 capacitor is connected across the supply side of the ballast and supplies leading reactive current.
3. Net current drawn from the distribution board falls, and the power factor measured at the fixture improves.
4. Lamp current is governed by the ballast, so the capacitance value is matched to the ballast rating and the fixture supply voltage.
5. Series-mounted discharge resistors keep the terminals safe after switch-off, and the electric fuse isolates the element on internal failure.

Reading the Model Code: Capacitance and Temperature Class

The plastic-shell family shares one 250 V, 85 ℃ platform, so the model number tells you the capacitance directly. Bar length below is drawn to scale against the largest value in that group.

Configuration Table: What Each Model Carries

Installation and Operating Boundaries

• Mount the body on the screw fitting inside the gear compartment so the housing does not touch the ballast or igniter.
• Connect the leads or VDE wire according to the luminaire wiring diagram; the film element is non-polarised, so orientation does not set the connection.
• Match the model voltage to the fixture supply voltage, and never combine values beyond the ballast design rating.
• Select 85 ℃ for open luminaires and 105 ℃ where measured ambient inside the housing is high, typically in enclosed high-bay fittings.
• Allow stored charge to bleed through the fitted resistance before touching terminals during service, and confirm with a meter.

Production Capacity and Quality Control Behind CBB80 Orders

Film slitting and element winding are handled in our own workshop, supported by inspection instruments on site. Eleven automatic slitting machines and fifteen imported automatic winding machines feed the capacitor lines, giving a daily output of 60,000 pieces across the product families.

The factory holds ISO 9001 quality management and ISO 14001 environmental management system certification, and capacitor products carry certificates including CQC, TUV, VDE, IMQ, UL and CE. Certificate scope for a specific model is confirmed at order stage, and we agree the acceptance items with you before production begins.
