As preferred version of the present invention, raw material components and the weight content of described high thermal resistivity chemical crosslinking polyolefin inner sheath and high thermal resistivity chemical crosslinking polyolefin oversheath are as follows, LEVAPREN500HV rubber: 10 parts; Ethylene propylene diene rubber 4045M:10 part; Dual-tert-butyl peroxy isopropyl base benzene: 0.6 ~ 1 part; Triallyl cyanurate: 0.2 ~ 0.4 part; Vinyl three ('beta '-methoxy ethyoxyl) silane: 0.2 ~ 0.5 part; Stearic acid: 0.5 ~ 1 part; Aluminium hydroxide: 30 ~ 35 parts; Fume colloidal silica: 6 ~ 10 parts; N550 carbon black: 0.6 ~ 1 part; Tissuemat E: 1.5 ~ 2.5 parts; Alkylated diphenylamine: 0.2 ~ 0.4 part; Firebrake ZB: 2 ~ 5 parts.This sheath obtains following beneficial effect: (1) LEVAPREN500HV rubber is along with the increase of wherein vinyl acetate content, the crosslinkable degree of sizing material, oil resistance, elongation at break can significantly increase, but when vinyl acetate content is greater than 55%, the heat-resisting quantity of LEVAPREN500HV rubber and elasticity can decline, and affect flexibility; The present invention is based on vulcanized rubber need to possess the high current-carrying capacity of high temperature resistant guarantee cable and select LEVAPREN500HV rubber; The molecular structure of LEVAPREN500HV rubber is saturated methine main chain simultaneously, and containing polarity side base, nonpolar methin groups and suitable activity, there is high flame retardant, heat-proof aging, oil resistance, and vulcanization crosslinking can be carried out by cheap peroxide, but the price of LEVAPREN500HV rubber is higher.(2) ethylene propylene diene rubber 4045M belongs to saturated copolymer, and not containing unsaturated double-bond, available peroxide cure, has excellent resistance to ozone aging, heat-resisting weather-resistant property, process industrial art performance, cheap, but oil resistance and poor adhesion.Adopt second Warburg Pincus rubber LEVAPREN500HV and ethylene propylene diene rubber 4045M to share and can play the two respective advantage, improve the overall performance of sizing material, reduce costs.(3) adopt aluminium hydroxide (i.e. hydrated alumina) as fire retardant; it contains 3 hydrones; start to decompose at 250 DEG C; discharge hydrone and absorb heat and reduce environment temperature; the steam discharged serves again the effect of combustable gas concentration in dilution gas phase, and the alundum (Al2O3) of generation and the carbide on burning polymer surface combine, and form diaphragm;
