Abstract: The present disclosure provides an anti-PID encapsulation adhesive film, a photovoltaic module, and a photovoltaic module manufacturing method. The anti-PID encapsulation adhesive film includes a base adhesive film layer, an insulating layer, and a conductive layer. The insulating layer is located on one side surface of the base adhesive film layer. The insulating layer has a grid structure. The grid structure includes grid lines and a plurality of hollow portions defined by the grid lines. The grid lines have a structure corresponding to gaps between cell pieces. The conductive layer includes a plurality of conductive portions. The conductive portions are arranged in the hollow portions in one-to-one correspondence. The volume resistivity of the conductive portions is less than 100 ?·cm.

Abstract: Disclosed are a crane and a control method therefor. The crane comprises a body, a boom, a luffing mechanism, a tension sensor, and a controller. One end of the boom is rotatably connected with the body. The luffing mechanism is respectively connected to the body and the boom. The tension sensor is disposed on the luffing mechanism, and the tension sensor is used for detecting a tension value of the luffing mechanism to the boom. The controller is electrically connected to the tension sensor and the luffing mechanism, and the controller is configured to determine that the arm length of the boom exceeds an arm length threshold if the tension value is greater than a tension threshold.
