Low-voltage line butterfly-type porcelain insulators are used in overhead power lines with a DC or power frequency AC rated voltage lower than 1000V for insulation and fixed conductors. According to its structure, it is divided into low-voltage pin insulator, low-voltage butterfly insulator, and low-voltage bobbin insulator. The ambient temperature of the installation and use site is -40℃~+40℃, and the altitude does not exceed 1000m.
Model Description
Needle type:
PD——Low voltage line pin insulator;
The number after "-" is the ordinal number of shape size, "1" is the one with larger size;
T, M, W——Code for installation and connection, T means straight iron legs, M means straight wooden legs, W means bent legs.
Butterfly:
ED——Low-voltage line butterfly insulator;
The number after "-" is the ordinal number of shape size, and "1" is the one with larger size.
Spool type:
EX——Low voltage bobbin insulator;
The number after "-" is the ordinal number of shape size, and "1" is the one with larger size.
