PVC-sheathed Mineral-insulated copper-clad cable | Mineral insulated copper cable with 2 conducting cores

However, costs of insulated cable and excavation are much higher than overhead construction.

It is advisable to provide bare conductor as ground connection, particularly in electronic circuits, because the insulated cable / conductor can work as secondary to lightening impulses and will make the earth float through induced secondary voltage.

In the 19th century and early 20th century, electrical cable was often insulated using cloth, rubber and paper.

Central metal-tipped insulated spike contacts cable core ; smaller spikes contact cable shield.

Braided line can contain an inner core of insulated wires which provide power to equipment located at the end of the cable, normally referred to as electric line, and provides a pathway for electrical telemetry for communication between the surface and equipment at the end of the cable.

The insulated junction of the tube and whip is fed from the coax and the lower tube end where coax cable enters has an insulated mount.

Wiring was performed using type NM nonmetallic sheathed cable, insulated with asbestos-reinforced rubber covered with jute and tar.

1. 5 mm < sup > 2 </ sup > mineral-insulated copper-clad cable ( known as pyro ) may also be used ( as mineral insulated cable can withstand heat more effectively than normal PVC ) though more care must be taken with regard to voltage drop on longer runs.

Electric line is the common term for the armored, insulated cable used to conduct current to downhole tools used for well logging.

The whole apparatus was suspended from a long cable, formed of two conducting wires, which winds around a windlass with metallic journals which are electrically insulated.

Electrical cable is routed overhead as an inexpensive way to keep it insulated from the ground and out of the way of people and vehicles.

An overhead line with bare conductors insulated by air is typically less costly than a cable with insulated conductors.

A shielded cable is an electrical cable of one or more insulated conductors enclosed by a common conductive layer.

If an unshielded insulated cable is in contact with earth or a grounded object, the electrostatic field around the conductor will be concentrated at the contact point, resulting in corona discharge, and eventual destruction of the insulation.

In 1957, Gore left a career with DuPont to pursue an idea for making electronic ribbon cable for use in computers that was insulated with polytetrafluoroethylene ( PTFE ).

The floating gate electrode has no connections to other parts of the integrated circuit and is completely insulated by the surrounding layers of oxide.

This patent has been called " the seminal patent of the insulated gate bipolar transistor.

Grandview Heights is often remarked upon as being a small insulated city very close to downtown Columbus and has one of the smallest school districts in the greater urban area in terms of student population.

The need to distinguish physically between the parameters ζ and µ can be clearly seen by considering the case of a body " A " that has a good electrical connection to Earth, but is sufficiently well insulated thermally from the Earth that it can be in ( approximate ) local thermodynamic equilibrium at a temperature different from that of the Earth.

In particular, moral hazard may occur if a party that is insulated from risk has more information about its actions and intentions than the party paying for the negative consequences of the risk.

Others suggest that a kind of valorization or " covert prestige " remained for many community members and that this complex pride has insulated the language from obliteration.

Wye service is recognizable when a line has four conductors, one of which is lightly insulated.

A study by the Universities of California and Potsdam found that the Karakoram glaciers are mostly stagnating, because, unlike in the Himalayas, many Karakoram glaciers are covered in a layer of rubble which has insulated the ice from the warmth of the sun.

Historically the Loess Plateau has provided simple yet insulated shelter from the cold winter and hot summer in the region, as homes called yaodong ( 窰洞 ) were often carved into the loess soil ; in medieval times of China people stayed here to grow rice ; some families still live in this kind of shelter in modern times.

It generally has a removable insulated lining, and it is usually knee-length.

Here are some examples: Weather balloon technology has helped firefighters with its short-range radios ; aluminized Mylar in satellites has made sports equipment more insulated ; laser optics systems have transformed the camera industry and life detection missions on other planets help scientists find bacteria in contaminated food.

The gun is insulated with a thermal sleeve and has an automatic compressed air fume extraction system instead of the usual bore evacuator.

It has a metal end split into two parts electrically insulated from each other, or two thin projecting metal electrodes about an inch apart, at an end of a shaft containing the batteries and mechanism.
