Line post insulators are a steel type insulator. Line post insulators are used for voltage 10kv to 132kv. Line post insulators can be used on the AC power lines in the general area and heavy polluted areas, and played a role of insulation and supporting conductors.

Line post insulators Category:
According to insulator material, line post insulators can be divided into porcelain line post insulators and composite line post insulators

Line post insulators with steel pins are generally used in high-voltage overhead transmission and distribution lines. Meet ANSI, BS, IEC and other standards. Line post insulators are typically used in the below voltage 132KV transmission and distribution systems.

According to models, line post insulators can be divided into four categories:
◆ Vertical mounting top lashing type, model ANSI57-1, ANSI57-2, 57-3, 57-4, 57-5
◆ Vertical mounting top clamp type, model ANSI57-11, ANSI57-12, 57-13, 57-14, 57-15
◆ Horizontal mounting the top clamp type, model ANSI57-21, ANSI57-22, 57-23, 57-24, 57-25
◆ Horizontal tilt top clamp installation type, model ANSI57-31, ANSI57-32, 57-33, 57-34, 57-35

Line post insulators used in transmission and distribution systems, porcelain insulators are generally gray and white colors, composite line post insulators are red and gray.
