EXTENSION TO POLE TOP
PROVIDES FOR EXTRA ARM
Additional Conductor Space Afforded on Pole Line
Without Decreasing Minimum Ground
Clearance
BY FRANK HUSKINSON
Having a pole already well filled with cross-arms and requiring six additional transmission conductors to parallel this line, an extra cross-arm was attached to the pole as shown in the illustration. Flat iron strips 3 in. by 0.5 in. (7.6 cm. by 1.3 cm.) were attached to the pole near the top and bent at right angles at a suitable distance above the pole top. The extra cross-arm providing for six insulators was attached to these iron strips by means of lag screws. This scheme gave additional height to the pole and eliminated the necessity of another pole line. It has given satisfactory service on a transmission line one mile in length.
