Abstract
The invention relates to the technical field of insulated materials, and in particular relates to a semiconductive external shielding material for a flame-retardant plastic insulated cable. The semiconductive external shielding material comprises the following components: 100.0 parts of modified rubber, 5 to 10 parts of superconductive carbon black, 15 to 25 parts of acetylene carbon black, 23 to 25 parts of vulcanization system and 0.1 to 0.5 part of antioxidant 300, wherein the modified rubber is acrylonitrile butadiene rubber. The semiconductive external shielding material ensures that residues do not exist in a cable insulation layer, and the long-term continuous running production can be realized when the cable is prepared by utilizing the semiconductive external shielding material, so that not only energy and materials are saved but also the cable is stable in quality and long in service life.
Description
Technical field
The present invention relates to Insulation Material technical field, especially one does incipient scorch cables with extruded insulation semiconduction external shield material.
Background technology
In 35KV and following circuit distributing system, cross-linked polyethylene insulated cable is widely used in the departments such as electric power, building, industrial and mineral, oil, chemical industry, instead of oil-impregnated paper insulation power cable and Some substitute PVC insulated power cable completely.The electric field stress that existing main insulating layer bears is little, but require surperficial resistance to solar light irradiation, resistance to thunderbolt is fast light heat aging performance is excellent, in order to protect major insulation, the inside and outside of main insulating layer must shield with semi-conductive layer.For this reason; IEC502 (1983) specifies: with isoprene-isobutylene rubber, polyethylene, crosslinked polyetylene insulated cable; voltage rating is when more than 1.8/3.0KV; use interior out semiconductor layer, its Main Function makes electric field distribution even, reduces strength of electric field; to reduce the air gap on conductor and insulation layer interface; improve the initial corona voltage of cable and the resistance to free discharge performance of cable, and reduce the temperature rise of insulation layer to a certain extent, to protect major insulation.
Summary of the invention
In order to overcome the deficiency of existing technology, the invention provides a kind of ultra-clean and doing incipient scorch cables with extruded insulation semiconduction external shield material.
The technical solution adopted for the present invention to solve the technical problems is: one does incipient scorch cables with extruded insulation semiconduction external shield material, and its component is as follows:
Modified rubber 100.0
Superconductive carbon black 5 ~ 10
Shawinigan black 15 ~ 25
Vulcanization system 23 ~ 25
Antioxidant 300 0.1 ~ 0.5
According to another embodiment of the invention, comprising described modified rubber is further nitrile rubber.
The invention has the beneficial effects as follows, cable insulation noresidue of the present invention, use this product manufacturing cable long-time continuous start to produce, not only save energy and material, and cable quality is stablized, long service life.
Embodiment
One does incipient scorch cables with extruded insulation semiconduction external shield material, and its component is as follows:
Modified rubber 100.0
Superconductive carbon black 5 ~ 10
Shawinigan black 15 ~ 25
Vulcanization system 23 ~ 25
Antioxidant 300 0.1 ~ 0.5
Described modified rubber is nitrile rubber.
Cable insulation noresidue of the present invention, use this product manufacturing cable long-time continuous start to produce, not only save energy and material, and cable quality is stablized, long service life.
