A simple and clear UV stable, weatherproof label for transformers with greater than 50 mg/Kg Polychlorinated Biphenyl (PCB) contamination.
common use of wound transformers, but sunken wound transformers are also seen. Fig. 6 PCB mounting options Planar transformers are often integrated, but here the tradeoffs between PCB layer build-up and transformer performance becomes an issue. Even a small modi-fication in the transformer, demands for a whole new
Two labels (Figure 5) are available for in-service equipment designed to use PCBs. These labels are serialized and have individual registration numbers at the bottom. The label shown in Figure 5a measures 15 cm x 15 cm and should be used on askarel transformers. The label shown in Figure 5b measures And do not trust a “Non PCB” label unless there is documentation of the Non PCB classification and have certification the transformers have not been serviced since that analysis was performed.
Central-Moloney Transformer Division of Colt Industries C-M will certify that any transformer manufactured after 1962 is PCB non-contaminated. Serial Number Interpretation Standard PCB, no PCBs, and non-PCB labels are available from EHSO CAUTION: Aged labels on electrical equipment may not accurately represent the PCB concentration of the equipment's contents. For example, sealed transformers labeled as containing non-PCB oil may become contaminated with PCBs during servicing. (b) As of October 1, 1978, each transport vehicle loaded with PCB Containers that contain more than 45 kg (99.4 lbs.) of liquid PCBs at concentrations of ≥50 ppm or with one or more PCB Transformers shall be marked on each end and each side with the M L mark as described in § 761.45 (a). PCB concentration assumptions applicable to transformers containing 1.36 kilograms (3 lbs.) or more of fluid other than mineral oil, see §761.2. For provisions permitting reclassification of electrical equipment, including PCB Transformers, containing >500 ppm PCBs to PCB-Contaminated Electrical Equipment, see § 761.30(a) and (h).
Sign In; My Account; Resource Center PCB mount transformer consists of metal core, an outer casing, mounting brackets and connecting terminals. PCB mount transformer is usually made of light materials so that they can be mounted on a computer board or over a chassis. The transformers are usually manufactured using semiconductor fabrication technology.
Review available materials, capabilities, and pricing from various board houses. Upload a Gerber file and make a few selections to place a custom PCB order.
<1. 3.b.6 Label. PMMA.
All transformers require registration with EHS and labeling with PCB level. Note:PCB-contaminated transformers with ≥50 but less than <500 ppm PCBs do not require the yellow PCB label, but must still be labeled with PCB ppm content. All PCB transformers should have already been drained, retrofilled with non-PCB mineral oil and tested,
PCB Congeners A PCB congener is any single, unique well-defined chemical compound in the PCB category.
PCB mounted transformers are
and label the equipment and remove it from use. The first problem that countries with PCB transformers still in operation have to face is how to locate and identify this equipment. A decision will then have to be taken as to when, and how, the contaminated equipment will be managed, reclassified and eventually eliminated.

Tech LET151 150 Watts 12 Volts Low Voltage Compact Electronic Transformer. 3.7V PCB Case 3.6V 4.2V Box, NEW Uline Blank Inventory Circle Labels 1" 5 label with settings inside the top part and is secured with a screw. If for some reason the PCB must be removed it must be handed carefully Unless different transformers are used, special precautions need to be taken.
These labels are serialized and have individual registration numbers at the bottom. The label shown in Figure 5a measures 15 cm x 15 cm and should be used on askarel transformers. The label shown in Figure 5b measures MIDWEST strongly recommends sampling the transformers by qualified personnel and testing the transformers for PCB and PCB Classification regardless of existing labeling. For decades, oil filled transformers have been labeled Non PCB by manufacturers.
