The invention discloses a high-voltage transmission line deicer, relates to the field of transmission line maintenance equipment, and solves the problems that an existing deicer cannot achieve simplestructure, no increase to a power transmission line and high deicing rate simultaneously. The high-voltage transmission line deicer comprises a deicing clamp and deicing plates, the deicing plates arefixed to clamping parts of the deicing clamp, and the two deicing plates which are oppositely arranged are used for clamping and fixing the power transmission line so that an ice layer on the power transmission line is removed; each deicing plate is divided into a cutting part and a crushing part from bottom to top; the cutting part is composed of M arc-shaped cutters, the M arc-shaped cutters are sequentially and evenly distributed in the length direction of the power transmission line, and cutting edges of the arc-shaped cutters are semicircular and used for cutting the ice layer in the circumferential direction of the power transmission line. The crushing part is composed of N protrusions and used for clamping the cut ice layer so as to crush the ice layer. The high-voltage transmission line deicer is mainly used for cleaning the ice layer of the power transmission line.

The invention discloses a mouseproof optical cable which comprises a cable core, an outer sheath, and a soft armor layer. The outer sheath coats the cable core. The soft armor layer coats the outer sheath and is made of a PA12 material. The structure of the mouseproof optical cable is simple, the soft armor layer can effectively prevent the optical cable from being bitten, the integrity of the optical cable is ensured, the weight of the optical cable is not increased, and the production cost is effectively controlled.

The invention relates to a power transmission tower angle steel connection joint. The power transmission tower angle steel connection joint comprises two principal materials, diagonal materials, diaphragm materials and auxiliary materials, wherein the principal materials are arranged in the vertical direction and serve as tower pillars, the diagonal materials are connected between the two adjacent principal materials, the included angle of the diagonal materials and the horizontal direction is smaller than 90 degrees, the diaphragm materials are horizontally arranged between the principal materials, and the auxiliary materials are connected with the principal materials, the diaphragm materials and / or the diagonal materials. The power transmission tower angle steel connection joint is characterized in that the principal materials which serve as the tower pillars comprise two or more principal material sections which are connected with one another in a head-to-tail mode; the tower pillars are composed of the principal material sections, the principal material sections comprise cross-shaped connecting plates which are perpendicular to each other and angle steel arranged on the crosswise intersected included angle portions. According to the power transmission tower angle steel connection joint, under the situation that the thicknesses of filler plates are different, connecting can be conducted among the principal material components according to the filler plate thicknesses obtained through actual calculation, the tower weight is reduced, it is guaranteed that the connection of the components is safe and reliable, and the economical efficiency of the tower is achieved.
