Abstract
The utility model relates to an outer sheath protection case of a three-phase high-voltage cable and discloses a sealed type cable sheath earth box. The earth box comprises a box body. The earth box is mainly characterized in that a plurality of cable sheath protectors are arranged inside the box body; gaps among the box body and the cable sheath protectors are filled with an epoxy resin waterproof sealing layer formed in a one-time molding way; and the two sides of the box body are provided with a plurality of insulation bearing frames. The sealed type cable sheath earth box has the advantages of small volume, high strength, convenient installation and good quality, etc. The problem that a conventional cable sheath earth box is dysfunctional due to long-standing condensation, moisture entries and water entries and so on is effectively solved. The power supply reliability of a power cable line is further effectively improved.
Description
Technical field
The utility model relates to a kind of outer jacket guard box of three-phase high-voltage cable.
Background technology
Existing cable sheath ground connection case long-standing such as condensation, advance tide, water inlet causes problem such as ground connection case inefficacy, has influence on the power cable line power supply reliability.
Summary of the invention
The utility model provides that a kind of volume is little, intensity is big, easy for installation, quality good, waterproof, anti-filthy, corrosion-resistant, non-maintaining effectively improves the closed type cable sheath ground connection case of power cable line power supply reliability.
The utility model is achieved by the following technical solution: a kind of closed type cable sheath ground connection case, comprise casing, its major technique feature is to be provided with several cable protective layer protectors in the described casing, and the space is filled with one-shot forming epoxy resin waterproof sealing layer between casing and the cable protective layer protector;
Described casing both sides are provided with several insulation load bearing frames.
The utility model is applicable to the high voltage power cable system, and its inner cable protective layer protector of installing can protect the outer jacket insulation of three-phase high-voltage cable to avoid superpotential infringement.Formed by integral insulation load bearing frame, the non-linear current limiting element of zero-clearance zinc oxide, one-shot forming epoxy resin watertight composition and stainless protection layer; have that volume is little, intensity is big, easy for installation, advantage such as quality is good; can effectively solve cable sheath ground connection case long-standing such as condensation, advance tide, water inlet causes problem such as ground connection case inefficacy, effectively improves the power cable line power supply reliability.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
As shown in Figure 1, this closed type cable sheath ground connection case comprises casing 1, is provided with 3 cable protective layer protectors 2 in the casing, and the space is filled with one-shot forming epoxy resin waterproof sealing layer 3 between casing and the cable protective layer protector; The casing both sides are arranged with 2 insulation load bearing frames 4 respectively.
Cable protective layer protector is made up of non-linear good zinc oxide resistance sheet; when normal operating conditions; resistor disc is high value; and when having served as voltage wave and invading; resistor disc is low-resistance, even flow through very big electric current, protector both end voltage value still is limited in the allowed band; thereby protected the protective coverings of cable insulation effectively, made it avoid superpotential damage.Zinc oxide resistance sheet stretches out the outer insulating sleeve 5 that partly is provided with of casing.
Claims (2)
1. a closed type cable sheath ground connection case comprises casing, it is characterized in that being provided with several cable protective layer protectors in the described casing, and the space is filled with one-shot forming epoxy resin waterproof sealing layer between casing and the cable protective layer protector.
