Embodiment Construction

[0015] Such as figure 1 As shown, a fan-shaped and circular fire-resistant cable with a Y-shaped nylon skeleton includes a cable core. The cable core includes a Y-shaped nylon skeleton 1, and the center of the Y-shaped nylon skeleton 1 is provided with a temperature-measuring wire core. The wire core includes two temperature-measuring wire core conductors 2, and the two temperature-measuring wire core conductors 2 are respectively wrapped with a heat-sensitive insulating layer 3 and twisted into bundles to form an outer wrapping layer 4. Two of the Y-shaped nylon skeleton 1 A control wire core is respectively arranged in the gap, and a ground wire core is arranged in another gap of the Y-shaped rubber skeleton 1, and the ground wire core includes a fan-shaped conductor 5 formed by twisting and extruding more than seven tinned copper wires. , the fan-shaped conductor 5 is wrapped with a cross-linked polyethylene insulating layer 6, the control wire core includes two circular co...

Abstract

The invention discloses a fan-shaped and round fire-resisting cable provided with a Y-shaped nylon framework. The cable comprises a cable core which comprises the Y-shaped nylon framework, wherein a temperature measurement cable core body is arranged at the center of the Y-shaped nylon framework, a control cable core body is arranged in each of two interspaces of the Y-shaped nylon framework, and a ground cable core body is arranged in another interspace of the Y-shaped nylon framework. The ground cable core body comprises a fan-shaped conductor which is wrapped in a crosslinked polyethylene insulation layer. Each control cable core body comprises two round conductors and silicon rubber insulation layers arranged outside the round conductors in a wrapping mode, and the two round conductors are twisted together in a pairing mode and then wrapped in a fire-resisting mica layer. The cable core is sequentially wrapped in a glass fiber fire-resisting layer, a steel-plastic strip longitudinal wrapping armor layer and a sheathe layer. According to the cable, a temperature measuring conductor and a control cable are combined through the Y-shaped nylon framework, temperature change occurring when the cable is used can be monitored, and then the warning function is achieved, fire disasters can be stopped or avoided in advance, and the stability of the cable is guaranteed.

Description

technical field [0001] The invention mainly relates to the technical field, in particular to a fan-shaped and round fire-resistant cable with a Y-shaped nylon skeleton. Background technique [0002] Fire is one of the major disasters that cause personal injury and property loss. With the development of high-rise buildings, the wide application of automation technology and the increase of various electrical equipment, the risk of fire has increased. In this regard, various countries and regions have successively formulated increasingly strict fire protection regulations. At present, ships, oil production platforms, petrochemical enterprises, power plants and power stations, self-control center buildings, hotels and restaurants, high-rise buildings, tunnels and subways all need fire monitoring and automatic alarm devices to facilitate fire extinguishing, alarming, lighting, communication, etc. Our country also attaches great importance to the fire safety and lifesaving of bui...
