Flexible cable for port

Abstract

The invention discloses a flexible cable for a port. The cable comprises conductors, insulation layers and an outer sheath; each conductor is formed by twisting a plurality of tinned copper conduction wires; an inflaming retarding ethylene propylene rubber insulation layer wraps each conductor; a nylon shielding layer and a tinned copper wire shielding layer respectively wrap the insulation layer to form one cable core; a wrapping belt layer wraps three stranded cable cores; inflaming retarding glass fiber ropes are arranged among the cable cores and the wrapping belt layer to be used as a filling layer; a nylon shielding layer and a tinned copper wire shielding layer are arranged outside the wrapping belt layer. The sheath layer made of a high-inflaming retarding, low smoke, no halogen and corrosion resistance neoprene rubber material wraps the tinned copper wire shielding layer. Insulation cable cores are arranged among the three cable cores. A nylon rope is arranged in the center of the cable. The flexible cable has low corrosion performance, the smoke during the burning of the cable is less, and the cable has the performances such as wear resistance, tear resistance, oil resistance, ozone resistance and high inflaming retarding.

Description

technical field [0001] The invention relates to the cable industry, in particular to a flexible cable for ports. Background technique [0002] Cables for port construction are mainly power transmission and distribution cables for port construction, temporary power distribution cables and lighting cables for construction sites, communication cables, cables for port machinery, etc. According to the natural conditions of the port construction site, the cables used are required to have mechanical properties such as resistance to dragging, pulling, and impact, and are required to be safe, reliable and leak-free. It is understood that, except for high-voltage power supply lines and lines that have been fixedly planned and laid, most of the cables used on the construction site are rubber insulated cables. [0003] Traditional soft cables for ports have a single structure and single function, which cannot meet the current port use environment. It has always been a difficult proble...

Problems solved by technology

[0003]The traditional port soft cable has a single structure and a single function, which cannot meet the current port use environment. It has always been difficult to solve the problems of wear resistance and twist prevention in the actual working environment question
