Engineers leave power cables slack when hanging them from pylons during summer to accommodate thermal expansion. As temperatures rise, the metal cables expand, and the slack allows for this natural expansion without creating excessive tension that could damage the cables or infrastructure. This practice ensures the integrity and longevity of the power transmission system while maintaining safety standards.

What is a pylon cable?
pylons are made of steel as it is a strong metal but cables themselves are copper. ps this is a terribe website
What tower supports a bridge cable?
In a standard suspension bridge the cables are supported by a Bridge Pylon or series of bridge pylons. The cables are supported upon these pylons and they serve to reduce the tension forces that would be required at the cable anchorages had the cables simply been installed straight across the bridge span.
What is a cable-stayed bridge?
A cable-stayed bridge is one where the deck is 'held up' by steel tensile cables which fan out from the bridge pylons or towers.
When electricians hang new power lines on a hot day they must not hang them too tight why?
If hung in hot weather, the cables will be in an expanded state and longer in length. Due to contraction of the cables in following cold weather, the cables will become shorter and could damage the connections on the poles or pylons. The loop between poles and pylons take this expansion and contraction of cable length into account.
What are the four main parts of the suspension bridge?
deck, span, abutment, cable, hanger, foundation, tower, and anchor
What does the term cat cables reference to?
'Cat cables' is a shortened term for 'category cables', which encompasses various standardised cables for Ethernet networks like the Cat 6 cable, or the Cat 5, or the Cat 5e. The wiring around the cat cables is usually colour-coded for ease of use by users and engineers.
How does a bridge stay together?
The towers are built first. Steel ropes are suspended from the towers. Special machines spin these into strong steel cables. Next, long steel cables called hangers are attached to the suspending bridge. Sections of the deck are lifted into place and fixed to the hangers.
Why must telephone cable be put up slack in summer?
In winter the cables will contract (shorten) due to the cold. If put up too tight in summer, on contraction, the cables would cause strain on the poles and fittings, and could even snap.
What is the plural of cable?
The plural of cable is cables.
Do you sell cable connectors for the printer cables?
Cable connectors are always avaible for printer cables.
Which AV cable is video?
In a set of cables with red, black (or white) and yellow cables, the yellow cable is a composite video cable.
What cable is used to connect PC to hub?
It depends on what kind of hub you mean. Some useful cables could be power cables, CAT 5e cables, fiber optic cables, etc.
