On core, the mesh aperture of aramid fiber mesh grid is 0.5~0.8mm, and the outer surface of the XLPE serving is covered with and can be caught in
The salient point of the mesh, tegillum with a thickness of 4~5mm in the XLPE；In the XLPE tegillum with a thickness of 11.2~
11.6mm。
As a kind of improvement of the utility model, the aramid fiber mesh grid with a thickness of 0.4~0.6mm.
As a kind of improvement of the utility model, the ceramic fibre layer of cloth with a thickness of 0.2~0.3mm.
As a kind of improvement of the utility model, one side position of outer surface of the XLPE serving is equipped with along its axial direction side
To the raised line successively extended, the top of the raised line is larger, and bottom is smaller；Another side position in the outer surface of XLPE serving is equipped with edge
The card slot that its axial direction successively extends, the cross-sectional profile profile phase one of the cross-sectional profile profile and the raised line of the card slot
It causes.
The utility model has the following beneficial effects: the utility model smart structural design, rationally coats on XLPE serving
Have an aramid fiber mesh grid, protect tegillum in XLPE be not affected or less affected by various light, heat, tide, low temperature, Acid-base Gas etc. erosion and
The damage of external mechanical power, prolongs the service life；And matched by tegillum in XLPE and XLPE serving, there is double-deck protect
Protection structure still has tegillum in XLPE to protect core even if XLPE serving is damaged, it is ensured that the conveying of normal electricity,
Securely and reliably；It is further provided with ceramic fibre layer of cloth, there is good low temperature resistant and high temperature strength performance, good flame retardation effect,
Cable comprehensive performance is improved, can be suitably used for some more rugged environments.
With reference to the accompanying drawing with embodiment, the present invention will be further described.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Referring to Fig. 1, a kind of single unmasked heavy wall type high voltage cable provided in this embodiment comprising twisted by strand copper wire
Tegillum 2, ceramic fibre layer of cloth 3, XLPE serving 4 and aramid fiber mesh grid 5, described in core 1 and XLPE made of conjunction
Tegillum 2, ceramic fibre layer of cloth 3, XLPE serving 4 and aramid fiber mesh grid 5 are successively coated on core 1 in XLPE, aramid fiber
The mesh aperture of fiber knitted net 5 is 0.5~0.8mm, and the outer surface of the XLPE serving 4, which is covered with, can be caught in the mesh
Salient point is not easy loose so that the cooperation between XLPE serving 4 and aramid fiber mesh grid 5 is more closely.The utility model knot
Structure is ingenious in design, and aramid fiber mesh grid 5 is rationally coated on XLPE serving 4, and tegillum 2 in XLPE is protected to be not affected or less affected by
The erosion of various light, heat, tide, low temperature, Acid-base Gas etc. and the damage of external mechanical power, prolong the service life；And pass through
Tegillum 2 and XLPE serving 4 match in XLPE, and there is double-layered protecting structure still to have even if XLPE serving 4 is damaged
Tegillum 2 protects core 1 in XLPE, it is ensured that the conveying of normal electricity, securely and reliably；It is further provided with ceramic fibre layer of cloth
