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. Production and use of insulated ladders requirements: insulated ladders (hereinafter referred to as ladder) of material, size, strength, etc. should be consistent with GB / T 17889.1-1999, GB / T 17889.2-1999 and other related requirements. Ladder production materials can be glass fiber, metal, wood and the like. Length straight ladder should not exceed 6m, extension ladder extends throughout the length should not exceed 11m, and the limit should be equipped with a device to ensure that the extension of the non-extension of at least 1m overlap. All staff before using a ladder, should receive training or guidance. Do not use on-site temporary production ladder. Do have vertigo or a result of taking drugs that may affect the balance of the body, such as personnel using a ladder. Check the insulation requirements of the ladder: the use of the newly acquired units in insulated ladders should be checked before being put into use during the inspection should be regularly checked and labeled to identify qualified. Meanwhile, the ladder should be checked before each use to ensure that it remains in good condition. Before using a ladder, make sure that safety does not exceed the maximum allowable load load. Faulty ladder should stop using labeled "banned" tab, and timely repairs. Occurs when the insulation ladder serious bent, deformed or irreparable destruction should be promptly scrapped. For ladder should be scrapped after the destruction, so as to ensure that it can no longer be used. Check the contents of the insulation ladder: ladder is suitable for the work function; ladder safety, whether or ladder rung deficient body breakage, fracture, corrosion, deformation, cracks; slip feet are secure good; ladders or without passing the examination identification; stopper is intact; rung or pedal state, whether dirt, oil or grease attachment; hardware is intact (rod, rivets, pole, nuts, bolts, foot); whether stretching ropes and pulleys intact; all fixed ladders, extension ladders and 2.4m above (including 2.4m) tying the word ladder is intact. After passing the examination, should be marked. You can brush the color ring, or paste labels high-quality, quality assurance under the premise that security fortunately, the more light the better the quality of the insulation ladder weight. Because of the need to use more high-performance raw materials, more advanced production technology, a more scientific design in order to reduce the product weight in the premise of ensuring safety. Lighter insulation ladder is more convenient to use. Electrical insulation ladder is to use glass fiber and epoxy resin as the main material and pultruded fiberglass ladder from the processing of profiles. It has high strength, corrosion resistance, appearance of merit and good electrical properties. Generally well tolerated "220kV / m" of power frequency test voltage. Therefore, as a safety glass can climb ladders tool power systems. As an alternative to metal ladders and bamboo ladder. Prevent induction electric shock accident caused by misuse and anti. Rigorously tested inspection glass ladders can also be used as high-pressure live working ladder. Electrical insulation ladder main technical parameters 1, insulation material density ≥1.95g / cm3 2, water absorption insulation materials 350Mpa 4, surface hardness 50 (Pap) 5, the insulation material surface pressure> 12kv (rms) 6, the design load > 880 (bovine) (a) the appearance, the assembly 1. Appearance: ladder shape of the components may not have sharp edges and corners should be inverted arc. 2. Assembly: YB3205 shall comply with the (two) general requirements 1. Materials should be pre-selected test 2. Aluminum alloy parts should be done anodized surface, shaft steel work surfaces should be protective coatings; insulation laminated type of material parts machined surface varnish application processing. 3. Surface roughness of the metal parts of the components to be machined surface ≤6.3 should rule and smooth. Insulation component surfaces should be smooth, no bubbles, wrinkles or cracks, abrasions and no obvious signs of overheating, the color should be gray (from yellowish green to brown) (c) of the power frequency voltage test 1.450KV / 1.8m, 1min test process should be no breakdown and other abnormalities occur. The material properties of the insulation material density insulation ladder ≥1.95g / cm3; insulating material absorption 350Mpa; surface hardness 50 (Pap); insulating material surface pressure> 12kv (rms); design load> 1500N insulation component surfaces should be smooth , no bubbles, wrinkles or cracks, abrasions and no obvious signs of overheating, the color is color.
