Structurally, the pointer consists of three parts: working, insulating and handle, made of electrically insulating fiberglass.
\nThe insulating part is located between the working part and the handle.
\nA colored marker ring is applied to the boundary between the working and insulating parts.
\nThere is a limiting ring of insulating material at the interface between the insulating part and the handle.
\nThe principle of operation of the indicator is based on the flow of capacitive current through the electrical circuit of the indicator (if there is voltage in the electrical installation being tested).<\/p>\n
TECHNICAL DATA<\/b><\/p>\n
The type of indicator is contact, operating without grounding the working part.<\/p>\n
The rated voltage tested in electrical installations is from 6 to 20 kV inclusive;<\/p>\n
Type of indication \u2013 combined (visual \u2013 main, acoustic \u2013 additional);<\/p>\n
The voltage indicator is designed for operation in the following conditions: a) continuously permissible operating temperatures: from minus 45 0\u0421 to plus 40 0\u0421;<\/p>\n
b) relative air humidity \u2013 up to 98% at a temperature of 25 0C;<\/p>\n
Overall dimensions:<\/p>\n
\u2013 length of the insulating part, mm \u2013 496;<\/p>\n
\u2013 handle length, mm \u2013 150;<\/p>\n
\u2013 total length (including the working part), mm, no more than \u2013 890.<\/p>\n
Indication voltage, kV, slightly more \u2013 1.5;<\/p>\n
Weight, kg, a little more \u2013 0.55.<\/p>","protected":false},"excerpt":{"rendered":"
The indicator meets the requirements of GOST 20493, TU U 21191464.005-2000 and is intended for use as the main electrical protective device when determining the presence or absence of voltage in electrical installations of alternating current with a frequency of 50 Hz and a voltage from 6 to 20 kV, including production voltage.<\/p>","protected":false},"featured_media":24349,"comment_status":"open","ping_status":"closed","template":"","meta":{"pgc_sgb_lightbox_settings":""},"product_brand":[],"product_cat":[1620],"product_tag":[],"class_list":["post-17053","product","type-product","status-publish","has-post-thumbnail","product_cat-elektroizmeritelnye_pribory_shtangi","first","instock","shipping-taxable","purchasable","product-type-simple"],"yoast_head":"\n
