The Sectional Strain Pole with splice, together with yokes, has been designed to withstand the mechanical straining of the conductors, when performing maintenance on the suspension or deadened insulator strings, where their lengths differ from the conventional standards.

The Sectional Strain Pole is composed of three parts:

Hot-end Strain pole (energized), Cold-end Strain pole (de-energized) and the fiberglass splice, which is the middle pole, intended for the joint of the hot-end and cold end poles.

These poles are manufactured with diam. 51 mm (2") Ritzglas® poles and each pole has a clevis-type cooper alloy head for connection to the yokes. The fiberglass splice is manufactured with a special manufacturing process, with reinforced fiberglass, outside of diam. 76 mm (3"). It is provided with holes every 100 mm (0.30 ft) enabling the assembly of the hot-end and cold-end poles, within pre-determined lengths.

The strain poles allow for different configurations with the strain jacks of following lengths: 305 mm (1 ft), 610 mm (2 ft) and 915 mm (3 ft), for extended overall length of the set. 

Hot-end or cold-end strain poles, fiberglass splice, strain jacks or counterpins can be ordered separately as replacement parts.

NOTE

Although the fiberglass splice is manufactured to standard lengths of 1.12 m (3.7 ft), the hot-end and cold-end strain poles can be ordered to special lengths, suitable to types and voltages of each company. For special lengths, which shall be according to the configuration of the strings, technical drawings must be provided to our Terex engineering department, in order to analyze the technical viability of the product.
