MOLYKOTE\u00ae: Special Lubricants for HV Connectors<\/h2>\n[\/vc_column_text][vc_column_text]The elastomer seal<\/strong>, which prevents moisture infiltration, requires proper lubrication to prevent microcracking<\/strong> during assembly and simplify the process. <\/span>
\n MOLYKOTE\u00ae 111 Compound<\/strong>
\n<\/a> e MOLYKOTE\u00ae HP-300<\/strong> Grease<\/strong><\/a> are the ideal solution for this need, offering excellent water resistance<\/strong> and superior sealing performance. In addition, both products have highdielectric strength<\/strong>, making them suitable for high-voltage environments.<\/span><\/p>\n

To ensure consistent electrical conductivity<\/strong> over time, the metal<\/strong> seal pins<\/strong> require adequate lubrication. MOLYKOTE\u00ae L-8030<\/strong> semi-dry lubricant is designed to reduce wear and<\/strong> fretting corrosion<\/strong> caused by vibration, reducing insertion force and protecting<\/strong> metal from oxidation. Field tests showed that the use of MOLYKOTE\u00ae L-8030<\/strong> did not affect electrical conductivity and maintained constant friction values for more than 250<\/strong> mating cycles<\/strong>.<\/span>[\/vc_column_text][\/vc_column][\/vc_row][vc_row type=”in_container” full_screen_row_position=”middle” column_margin=”default” column_direction=”default” column_direction_tablet=”default” column_direction_phone=”default” scene_position=”center” text_color=”dark” text_align=”left” row_border_radius=”none” row_border_radius_applies=”bg” overflow=”visible” overlay_strength=”0.3″ gradient_direction=”left_to_right” shape_divider_position=”bottom” bg_image_animation=”none”][vc_column column_padding=”no-extra-padding” column_padding_tablet=”inherit” column_padding_phone=”inherit” column_padding_position=”all” column_element_direction_desktop=”default” column_element_spacing=”default” desktop_text_alignment=”default” tablet_text_alignment=”default” phone_text_alignment=”default” background_color_opacity=”1″ background_hover_color_opacity=”1″ column_backdrop_filter=”none” column_shadow=”none” column_border_radius=”none” column_link_target=”_self” column_position=”default” gradient_direction=”left_to_right” overlay_strength=”0.3″ width=”1\/1″ tablet_width_inherit=”default” animation_type=”default” bg_image_animation=”none” border_type=”simple” column_border_width=”none” column_border_style=”solid”][divider line_type=”No Line” custom_height=”20″][vc_column_text]\n
