11kv polymer pin insulator price

    The old pin insulators are classified into five classes according to the rated voltage: 6, 10, 15, 20 and 35kV. Depending on the installation method, depending on the insulation structure, iron crossbars with shorter threads and wooden crossbars with longer threads are used. Divided into ordinary and reinforced pin insulators. Pin insulators with high voltage ratings have large dimensions and the lower edge of the umbrella is also deep. High voltage pin insulators are P-6T(M), P-10T(M), PQ-10T(M), P-15T(M), P-20T(M), PQ-20T(M), P-35T (M) and other models. P stands for pin type, Q stands for reinforced insulation, 10, 15, etc. stand for rated voltage level, T stands for iron cross-leg straight, M for wooden cross-leg straight.

    The new model pin insulators have a rated voltage of 10kV and are divided into three types: common type, type 1 reinforced insulation type and type 2 reinforced insulation type. The meanings of the symbols in the model are as follows:

   P type ordinary type Pin Insulator; PQ1 reinforced insulation type 1 (medium earth type) pin type insulator; PQ2 reinforced insulation type 2 (especially heavy) insulator; B-the upper part of the side groove of the porcelain groove, except the bearing surface, are Semi-conductive glaze; T-band, porcelain and feet glued directly, iron-loaded; L-without feet, porcelain pieces threaded to feet; LT-with feet, porcelain and feet threaded, iron-loaded; number 10 after the dash The rated voltage is 10 kV; the number 16,20 after the T indicates the diameter of the thread at the lower end.
