ballasts造句

Also, some ballasts manufactured after 1978 contain PCBs or the carcinogenic chemical DEHP.

Used for testing the transistors of electronic ballasts, energy-saving lamps.

Railway applications - Rolling stock - D. C. supplied electronic ballasts for lighting fluorescent lamps.

Fluorescent lighting ballasts may contain PCBs and must be disposed in accordance with state and federal regulations.

For these reasons, all fluorescent lighting ballasts which are not specifically labeled "no PCBs" must be suspected to contain PCBs.

The model of high intensity discharge (HID) lamps contributes a lot to the designing of electronic ballasts.
