The altitude of the installation site shall not exceed 1000m;<BR>2. The ambient air temperature does not exceed+40. C£¬ And its average temperature value within 24 hours does not exceed+35. C£¬ The lower limit of ambient air temperature is -5. C;<BR>3. The highest temperature is+40. At C, the relative humidity of the air does not exceed 50%; Higher relative humidity is allowed at lower temperatures, up to a maximum of 80%;<BR>4. Installed in non explosive and flammable hazardous media, with no gas or dust (including conductive dust) in the medium that can corrode metals and damage insulation;<BR>5. The installation location should have no severe vibrations or bumps, and the installation inclination should not exceed 5 °;<BR>6. The installation location is not directly exposed to sunlight, and there is no rain, snow, or severe mold present.<BR>The structural features of this type of transformer are cast insulated busbar type, with a secondary winding wound on the iron core and a base at the bottom for fixed installation.<BR><BR>Main technical parameters of LMZ-1KV mining current transformer<BR><BR> <TABLE style="WIDTH: 650px; BORDER-COLLAPSE: collapse" cellSpacing=0 cellPadding=1 width=650 align=center border=1> <TBODY> <TR> <TD rowSpan=2>Product model</TD> <TD rowSpan=2>Rated primary current</TD> <TD rowSpan=2>Rated secondary current</TD> <TD colSpan=2>Accuracy level and rated output<BR>COS¦Õ=0.8</TD> <TD rowSpan=2>number of turns through the core</TD> <TD rowSpan=2>Rated insulation level</TD></TR> <TR> <TD>one</TD> <TD>three</TD></TR> <TR> <TD rowSpan=14>LMZ-1</TD> <TD>fifty</TD> <TD rowSpan=7>five</TD> <TD rowSpan=14></TD> <TD rowSpan=7>two</TD> <TD>three</TD> <TD rowSpan=14>1/3.6</TD></TR> <TR> <TD>seventy-five</TD> <TD>two</TD></TR> <TR> <TD>one hundred</TD> <TD>two</TD></TR> <TR> <TD>one hundred and fifty</TD> <TD>one</TD></TR> <TR> <TD>two hundred</TD> <TD>one</TD></TR> <TR> <TD>three hundred</TD> <TD>one</TD></TR> <TR> <TD>four hundred</TD> <TD>one</TD></TR> <TR> <TD>fifty</TD> <TD rowSpan=7>one</TD> <TD rowSpan=7>five</TD> <TD>three</TD></TR> <TR> <TD>seventy-five</TD> <TD>two</TD></TR> <TR> <TD>one hundred</TD> <TD>two</TD></TR> <TR> <TD>one hundred and fifty</TD> <TD>one</TD></TR> <TR> <TD>two hundred</TD> <TD>one</TD></TR> <TR> <TD>three hundred</TD> <TD>one</TD></TR> <TR> <TD>four hundred</TD> <TD>one</TD></TR></TBODY></TABLE> <P align=center><BR>LMZ-1KV mining current transformer<BR></P>
