Use insulated ladders Features: 1, high pressure safety aids fiberglass ladder, aluminum step bars, 35KV voltage in the following use, stable and lightweight. 2. EHV-resistant glass fiber insulation ladder, fiberglass step bars, special fabrication, pressure in 220AKV following live action. (1) non-conductive, the appearance of new, beautiful (2) corrosion resistance (with acid and alkali resistance, and many organic solvents and salt air, corrosion liquid medium. Based on the actual use of the occasion demands, may choose to use economically phthalic type, isophthalic type, vinyl resin matrix materials do), resistance Kuxiu, fade-resistant (3) light weight, convenient transfer (4) low water absorption, flame resistance (typically convey flame retardant grille rate (ASTM E-84) does not exceed 25; upscale grill flame retardant vinyl convey the rate does not exceed 10. The oxygen index of not less than 28 (GB 8924)) (5) high-strength, lightweight. The principles of the invention insulating ladder electronic band theory that electrons in solids present in only allows only a certain energy state, and the energy state may be formed separated from each other band. Electron tends to occupy the lowest energy band, the valence band is insulation ladder can be filled at the absolute zero of the highest energy band, the valence band is called the conduction band above the band, between the valence band and the conduction band the gap is known as the energy gap. Above absolute zero, the valence band is excited electronic parts and transition to the conduction band, becoming the conduction band electrons and valence band holes left. According to band theory, be able to fill or empty with electronic band does not contribute to conductivity, electrical conductivity derived only half full band, conduction band electrons and valence band holes collectively known as carriers. Metallic conduction band is partially filled, so there is a good electrical conductivity. For semiconductors and insulation ladder, insulation ladder at absolute zero degrees valence band is filled, but there is no conduction band electrons. At room temperature, the semiconductor due to a smaller energy gap, can be formed by thermal excitation of electron-hole pair, which has a certain conductivity. In contrast, the vast majority of insulation ladder generally has a very large band gap, valence band electrons are excited to the conduction band is difficult, and therefore the carrier concentration is extremely low insulation ladder, correspondingly conductivity is very low, or that this material insulation. Note the use of a matter before, before each use ladders, ladders surface must be carefully examined, spare parts, such as the existence of a rope cracks, severe abrasion and impact damage to insulation ladder safety when used. 2, when using ladders to select a hard, flat surface, in order to prevent the risk of side crooked. 3. Check that all contact with the ground a good foot of the ladder to prevent slipping. 4. If using a ladder height of more than 5 meters, be sure to pull in the upper part of the establishment of more than F8 ladders. 5, dizziness, vertigo, drink or unwell Do not use a ladder. 6, in the doors, windows all around the work, you must first fixed windows, to avoid opening and closing windows hit the ladder. 7, using a ladder under windy conditions, or try to be careful not to use. 8, the proper use of ladders most suitable height, and never attach or put anything down to increase the height of the ladder. 9, without the permission of the manufacturer, ladders never attach other structures, and never use and maintenance of a damaged ladder. 10, when the ladder lift, non-holding crossbars to prevent cuts finger. When using an absolute prohibition of the workload over the ladder. 2, the foot of the ladder with non-slip effect. But people still need to have a direct hand hold the ladder awakened protection (while placing the ladder side crooked), and their feet stepped foot ladder to prevent the occurrence of foot movement. 3, must wear flat shoes when climbing the ladder to avoid slipping accidents. 4, when climbing ladders or working, always keep the body in the middle of the ladder rungs bang, keep the body upright, not out into the outside, or you might lose balance because of accidents. 5, it was on a ladder when the shift is strictly prohibited. 6, allowing only one person to climb the ladder or ladder. After using the work is completed, please ladder wipe clean, dry place to save.
