SECTIONAL STRAIN POLE (WITH SPLICE)
Designed to withstand the mechanical strain of conductor cables while maintaining suspension or anchor insulator strings where their lengths differ from conventional standards.
This pole consists of three parts: hot-end pole (energized), cold-end pole (de-energized), and the fiberglass splice, which is the central tube responsible for joining the live and cold end poles.
Constructed with Ø 51 mm RITZGLAS® tube, each has a clevis-type bronze alloy head for connection to the yokes. The fiberglass splice is manufactured by a special process, with Ø 76 mm exterior reinforced fiberglass, and has equidistant holes every 100 mm, making it possible to assemble the hot-end and cold-end poles, within pre-established lengths.
The poles also allow combinations with strain jacks in lengths 305, 610 and 915 mm for additional gain in overall assembly length.
Hot or cold-end poles, fiberglass splice, strain jack, or cotter pins can be purchased separately as spare parts.
NOTE
Although the splicing fiberglass splice is manufactured to a standard length of 1.12 m, dead and hot-end poles can be purchased with special lengths to suit the types and strains of each company's networks. For such supplies, which will depend on the arrangements of the strings, their design must be sent to our engineering department for technical feasibility analysis.

 | - FLV10460-1 The installation of the locknut is recommended for shortly after placing the trunnions on the strain jacks as additional safety during the strain operation, and acts as a support in the trunnions. |
 | - RE401-2066 / RE401-2068 The trunnions (large and small) are specially designed for coupling the yokes on the strain poles. They are made of bronze alloy and have bearings to make them light during their rotation on the strain jacks, which is done through the ratchet wrench (RM1948-3). |
 | - RE401-0138 The adjustable pole clamp is constructed of heat treated aluminum alloy and designed for coupling the yokes to the strain poles on the hot-end. A mobile device in this tool allows (manually or via stick) adjustment and displacement of the pole clamp for better positioning on the Strain Pole's steel pins. |
 | - RE401-1998 / RV401-0157 / RV401-0158 The Tongue type Strain Jacks are used in coupling to the strain poles as an adjustment tool in insulator string straining. They are coupled through the eye of the strain pole through the head in one of its ends. |
 | - FLV17755-1 Trunnion Gauge. Made of steel, this gauge (also known as “Go/No-Go”) is an essential tool for periodically checking the trunnion threads to check for wear on the trunnion threads. This gauge is threaded, with increased thickness by 0.5 mm. When testing, if the trunnion allows its insertion, even partially, a thread wear of more than 0.5 mm will be identified, thus ensuring that it is unfit for use. |
 | - RH4785-1 / RH4785-2 / RH4785-3 / RT400-0025 Clevis type strain jacks are used in connection with the clevis-eye strain poles (RH1949-113 / RC400-0612 and RC400-0613) as an adjustment tool for straining insulator strings. They are coupled through the eye of the strain pole through the head in one of its ends. |
 | - RM1948-3 The reversible ratchet wrench is specially developed for hex nuts and trunnions that make up the single or double strain carrier assembly. |
